OTICON ACTO POWER BTE (WL) Behind-The-Ear (BTE) Hearing Aid

The Oticon Acto Power BTE (WL) Behind-The-Ear Hearing Aid is a powerful digital hearing solution designed for individuals who require increased amplification while also benefiting from automatic sound processing, noise management, directional technology, feedback control, binaural coordination, and wireless accessory compatibility. The Acto family was built on Oticon's RISE 2 platform, a digital processing platform developed to provide improved sound processing and an expanded frequency bandwidth compared with earlier generations. Oticon describes Acto as a hearing solution for people with hearing loss ranging from mild to severe, with the Power BTE configuration providing substantially greater output than the standard Acto BTE. The Acto Power BTE is a conventional high-power Behind-The-Ear configuration. Oticon's technical data specifies a peak OSPL90 of 127 dB SPL, peak full-on gain of 61 dB, a frequency range of approximately 100–6000 Hz, and a size-13 zinc-air battery configuration. Oticon's product information gives a calculated battery life of approximately 215 hours under standardized conditions. Actual battery life varies according to hearing loss, gain settings, wearing time, sound environment, wireless use, battery quality, and other factors. The standard Acto Power should be distinguished from the Acto Pro Power. The standard Acto has 6 fitting bands, while Acto Pro has 8 fitting bands. Both platforms include important technologies such as directional processing, noise management, binaural coordination, feedback cancellation, ConnectLine compatibility, and FM/DAI support, but the Pro model has a higher technology level and additional processing capabilities. Powerful Amplification The primary purpose of the Acto Power BTE is to provide higher levels of amplification for individuals whose hearing loss cannot be adequately addressed by lower-power hearing-aid configurations. The technical data lists a peak full-on gain of 61 dB and a peak OSPL90 of 127 dB SPL for the Acto Power BTE. These figures describe the maximum technical capability of the instrument under standardized test conditions rather than the amount of amplification that every wearer will receive. The audiologist determines the actual gain according to the user's audiogram, speech understanding, loudness tolerance, acoustic coupling, and communication requirements. The objective is not simply to make all sounds louder. A properly fitted power hearing aid should provide appropriate access to speech and environmental sounds while keeping loudness within a comfortable and useful range. Behind-The-Ear Design The Acto Power uses a traditional Behind-The-Ear design, with the hearing-aid electronics positioned behind the ear. This format is well suited to higher-power amplification because it provides sufficient space for the amplification components and a larger size-13 battery. The device can be connected to an appropriate earmould or acoustic coupling according to the user's hearing loss and required amplification. A BTE format can also be practical for individuals who prefer accessible controls and straightforward handling. Compared with very small custom hearing aids, a BTE can be easier for some users to put on, remove, clean, and maintain. For a Power fitting, the acoustic coupling is particularly important because the earmould or tubing contributes to sound delivery, retention, comfort, and feedback control. RISE 2 Digital Processing Platform The Acto family is built on the RISE 2 platform, which provides the digital processing foundation for the hearing aid. Oticon describes the platform as providing enhanced processing power and an 8 kHz bandwidth, contributing to a fuller and more balanced sound presentation. The platform processes incoming sound digitally and allows the audiologist to tailor amplification and processing according to the individual hearing profile. The hearing aid is designed to respond differently depending on the surrounding acoustic environment. This is important because a user may spend the day moving from a quiet home to outdoor surroundings, conversations with family members, a workplace, a shop, or a social gathering. Six Fitting Bands The standard Acto is documented with 6 fitting bands. Fitting bands allow the audiologist to adjust amplification across different portions of the frequency range. Hearing loss is often not identical at every frequency. An individual may have relatively better low-frequency hearing but greater difficulty hearing high-frequency speech information, while another user may have a different audiometric configuration. The six-band architecture gives the hearing professional several areas in which to make frequency-specific adjustments. This helps provide a more individualized fitting than applying the same amount of amplification across the complete frequency range. 8 kHz Bandwidth The Acto platform is documented with an 8 kHz bandwidth. Bandwidth determines the range of frequencies available for processing and fitting. High-frequency information can be important for speech clarity, especially for certain consonants, while lower-frequency sounds contribute to voice fullness and environmental awareness. The available bandwidth does not mean that maximum high-frequency amplification should be provided to every user. The audiologist determines the appropriate fitting range and gain based on the individual's hearing loss and comfort. Multi-Band Adaptive Directionality One of the key Acto technologies is Multi-Band Adaptive Directionality. Oticon identifies this feature for both Acto Pro and standard Acto. Directional microphone processing can help the hearing aid emphasize useful sounds while managing selected competing sounds arriving from other directions. The adaptive design allows the hearing aid to modify its response according to the listening environment instead of maintaining one fixed directional setting. For example, during a face-to-face conversation, the main speaker may be positioned in front of the wearer while competing sounds come from the sides or behind. Adaptive directionality can be useful in restaurants, meetings, family gatherings, offices, shops, and other situations where several sound sources are present. TriState Noise Management The Acto incorporates TriState Noise Management. Background noise can come from traffic, fans, air-conditioning systems, machinery, kitchen appliances, other conversations, and many other sources. Noise-management technology is designed to reduce the prominence of selected unwanted background sounds while maintaining access to speech and useful environmental information. The TriState system allows different processing responses according to the detected listening situation. The purpose is not to eliminate all background sound. Environmental awareness is still important. Instead, the system aims to provide a more comfortable balance between relevant speech and competing environmental noise. DecisionMaker2 Another important Acto feature is DecisionMaker2. Oticon lists DecisionMaker2 among the standard Acto features. DecisionMaker2 forms part of the hearing aid's automatic environment-management approach. A hearing aid needs to respond differently when the wearer is in quiet surroundings compared with situations containing speech and background noise. DecisionMaker2 contributes to the automatic selection and management of appropriate processing according to the acoustic environment. This can help make everyday use easier because the user does not have to manually adjust the hearing aid every time the listening situation changes. Binaural Coordination The standard Acto includes Binaural Coordination. When two compatible Acto hearing aids are fitted together, binaural coordination allows selected functions to be coordinated between the left and right devices. This can make everyday operation more convenient for bilateral users. For example, when a user changes an appropriate control on one hearing aid, the corresponding function can be coordinated with the other hearing aid when the system has been programmed for that operation. Binaural coordination should be distinguished from the more advanced binaural synchronization features found in some higher-level Oticon generations. Binaural Dynamic Feedback Cancellation 2 The Acto family also includes Binaural Dynamic Feedback Cancellation 2, commonly referred to as DFC2. Oticon lists this feature for standard Acto as well as Acto Pro. Feedback occurs when amplified sound escapes from the ear and returns to the microphones, producing an unwanted whistling or squealing sound. Feedback cancellation is particularly important in Power hearing aids because higher amplification can increase the possibility of acoustic feedback. The feedback system is designed to help maintain stable amplification while reducing unwanted sounds. However, electronic feedback cancellation does not replace a correctly fitted earmould or acoustic coupling. Ear anatomy, tubing, acoustic sealing, gain, and the physical condition of the earmould all influence feedback performance. Speech and Sound Quality The Acto Power is designed to provide useful access to speech while maintaining a balanced representation of environmental sound. The RISE 2 platform provides digital processing across the available bandwidth and supports automatic adjustments to different listening environments. Oticon describes Acto as being designed to provide improved comfort, clarity, and understanding through technologies such as Multi-Band Adaptive Directionality, TriState Noise Management, and DecisionMaker2. Speech understanding depends on many factors, including the degree and configuration of hearing loss, speech discrimination, distance from the speaker, room acoustics, and background noise. Therefore, the device should be viewed as a tool for improving access to sound rather than a guarantee of perfect speech understanding in every environment. Comfort and Listening Experience Comfort is an important part of successful hearing-aid use. A hearing aid should provide sufficient amplification without creating unnecessarily loud or uncomfortable sound. The Acto Power's automatic processing can help manage changes in sound conditions, while professional fitting allows the audiologist to balance amplification and comfort. Users may require several follow-up appointments before the hearing aid feels fully natural. This is especially relevant for people who are new to amplification or who are moving from a lower-powered hearing instrument to a Power BTE. Wireless Connectivity The WL version of the Acto Power provides wireless capability within Oticon's wireless accessory ecosystem. Oticon's Acto documentation identifies the family as ConnectLine enabled, with support for compatible wireless accessories. The wireless ecosystem can expand the usefulness of the hearing aids beyond ordinary microphone-based listening. Compatible accessories can support applications such as television listening and communication with supported external devices. The Acto belongs to an older generation of Oticon wireless technology. Therefore, it should not automatically be described as having the modern direct Bluetooth connectivity available on current Oticon hearing aids. The exact accessory and external-device compatibility should be verified before purchase. ConnectLine Compatibility The Acto Power is ConnectLine enabled. ConnectLine accessories can provide an additional pathway for supported external audio. For example, a compatible television accessory can transmit supported television audio to the hearing aids. This can be useful when the wearer finds it difficult to distinguish television dialogue from music, sound effects, or other sounds in the room. Other compatible ConnectLine accessories can provide additional communication and audio functions depending on the configuration. FM and Direct Audio Input The Acto platform supports FM and Direct Audio Input (DAI) options. FM systems can be useful in educational, professional, and specialized communication situations where a speaker's voice needs to be transmitted more directly to the listener. Direct Audio Input provides a wired pathway from compatible equipment to the hearing aid. These options add versatility for users who need specialized communication or audio connections. In-Situ Audiometry The Acto platform supports in-situ audiometry through the fitting system. In-situ audiometry provides an additional method of obtaining information about the user's response through the hearing instrument. This can support fine-tuning and individualized programming during the fitting process. The audiologist can consider these measurements together with the conventional hearing assessment and the user's own comments regarding sound quality and speech understanding. NAL-NL1 and DSL Fitting Options Oticon's Acto documentation identifies support for NAL-NL1 and DSL v5.0a m[i/o] fitting approaches. Fitting formulas provide the audiologist with a structured starting point for determining appropriate amplification based on the individual's hearing thresholds. The initial settings can then be adjusted according to loudness comfort, speech access, acoustic coupling, personal preferences, and real-world listening experience. Professional programming is particularly important with a Power hearing aid because the appropriate amount of amplification varies significantly between users. Memory and Programmable Settings The Acto platform includes Memory functionality. Memory allows selected hearing-aid settings and programs to be retained for use in different listening circumstances. Depending on the individual's fitting, separate settings can be created for everyday listening, noisy situations, telephone use, music, or other requirements. The exact program arrangement should be customized by the hearing professional rather than assumed to be identical across all Acto Power instruments. Three Identities Oticon's Acto product information lists three identities for the Acto and Acto Pro platforms. These personalization options are intended to provide different starting points for sound preference and hearing-aid fitting. Different users may prefer different balances of clarity, comfort, and environmental awareness. The audiologist can use the available identities as part of the overall personalization process. Size 13 Battery The Acto Power BTE uses a size 13 zinc-air battery. Oticon's published product information gives a calculated battery life of approximately 215 hours for the BTE Power configuration under the stated measurement conditions. Real-world battery life may vary depending on amplification levels, daily wearing time, listening environment, wireless accessory use, battery quality, and other factors. Users should carry spare batteries when travelling or spending long periods away from home. The battery compartment should be kept clean and dry, and batteries should be replaced according to professional instructions. Technical Power Specifications Oticon's technical data for the Acto Power BTE lists a peak OSPL90 of 127 dB SPL, HF average OSPL90 of 120 dB SPL, peak full-on gain of 61 dB, HF average full-on gain of 55 dB, and a measured frequency range of approximately 100–6000 Hz. The published data is based on standardized hearing-aid measurement methods. These figures describe the device's technical performance rather than an individualized prescription. A person's actual programmed output can be significantly lower and should be selected according to the audiogram and comfortable hearing levels. Because the Acto Power is a higher-output device, accurate fitting and verification are especially important. Acoustic Coupling and Earmould The acoustic connection between the hearing aid and ear is an important part of Power BTE performance. The Acto Power can be fitted with an appropriate hook and earmould or other compatible acoustic arrangement according to the user's hearing loss. The correct acoustic coupling should provide adequate sound delivery while maintaining comfort and retention. For higher levels of amplification, an appropriate acoustic seal can also help reduce the likelihood of feedback. The earmould and tubing should therefore be checked periodically for wax accumulation, moisture, cracks, blockage, or changes in fit. Who Can Benefit From Oticon Acto Power BTE? The Oticon Acto Power BTE may be considered for individuals who: Require stronger amplification than a standard hearing-aid configuration Have moderate-to-severe or more significant hearing loss within the instrument's fitting capability Prefer a traditional Behind-The-Ear design Want a size-13 battery-powered hearing aid Need individualized digital amplification May benefit from Multi-Band Adaptive Directionality Spend time in environments with background noise Want automatic noise management Need feedback management for higher amplification Use one or two hearing aids Want wireless functionality through compatible Oticon accessories May use ConnectLine, FM, or Direct Audio Input systems Prefer a hearing aid with accessible controls and conventional BTE handling Final suitability should always be determined through a professional hearing evaluation. Professional Audiological Fitting Professional fitting is essential for achieving appropriate performance from the Acto Power. The audiologist should first assess the hearing thresholds and determine the amount of amplification required. The appropriate earmould or acoustic coupling should then be selected based on hearing loss, ear anatomy, gain requirements, feedback considerations, and comfort. The device can be programmed using an appropriate fitting formula and further adjusted according to real-world listening experience. Follow-up appointments are important because the wearer may discover that certain environments require additional adjustments. The hearing professional can fine-tune amplification, directionality, noise management, feedback control, program settings, and other available features. Maintenance and Care Regular maintenance helps preserve reliable hearing-aid performance. The device should be protected from excessive moisture, extreme heat, dust, and unnecessary physical impact. Oticon's general cleaning guidance recommends using a soft, dry cloth and specifically states that hearing aids should not be washed or immersed in water or other liquids. The earmould and tubing should be checked regularly for wax buildup, moisture, blockage, cracks, or changes in fit. If the hearing aid develops persistent feedback, distorted sound, intermittent output, reduced amplification, or unusual battery consumption, it should be inspected by a qualified hearing professional. Internal repairs should not be attempted by the wearer. Everyday Listening Applications The Acto Power can be professionally programmed for a wide variety of everyday listening environments. At home, it can support conversations with family members and access to household sounds. During face-to-face communication, directional processing can help manage competing sound. In restaurants and social environments, Multi-Band Adaptive Directionality and TriState Noise Management can provide automatic management of competing background sound. For television and compatible external audio sources, ConnectLine accessories can provide additional wireless listening options. For selected educational or specialized environments, FM and Direct Audio Input can provide additional communication pathways. For bilateral users, Binaural Coordination can help coordinate selected controls between the two hearing aids. Difference Between Acto Power and Acto Pro Power The Acto Power should not be confused with the Acto Pro Power. Oticon's product comparison identifies 6 fitting bands for Acto and 8 fitting bands for Acto Pro. The Pro version also has additional technology-level features, while both platforms share technologies such as Binaural Coordination, Binaural Dynamic Feedback Cancellation 2, Multi-Band Adaptive Directionality, ConnectLine, FM/DAI, memory, and 8 kHz bandwidth. This distinction is important when preparing a product catalogue because specifications from Acto Pro should not be presented as standard Acto Power features.
