TelecoilTelecoilThe hearing aid is able to pick up audio from landline telephones or public audio systems without using its acoustic microphones. This minimizes background noise and improves clarity and understanding, even over great distances. At performing arts venues, events, government meetings, etc., look for assistive listening systems (hearing loop, FM, and infrared systems), which must be provided at no cost under the Americans with Disabilities Act (ADA) and other international regulations.

Adjustment BandsAdjustment BandsThese are frequency-divided sections that can be adjusted in a hearing aid in order to amplify sounds. Although there are rarely more than 10 frequencies measured in a hearing assessment, having more bands that can be adjusted may allow for improved speech understanding and user comfort.

Adjustment SynchronizationAdjustment SynchronizationThis feature allows for a more pleasant listening experience by ensuring that both hearing aids process sound the same way. If one hearing aid changes its processing in response to noise or speech, it will send a wireless signal to the other hearing aid so both process sound in the same way.

Automatic Phone ProgramAutomatic Phone ProgramHearing aids with this feature can detect when a phone is placed near them and automatically switch to a phone program. In this setting, the hearing aids will reduce background noise and increase the volume of the phone.
PhoneNow™PhoneNow™PhoneNow is a feature that automatically switches the hearing instrument to a phone program. If there is no telecoil in the hearing instrument, an acoustic phone program with a frequency response optimized for use with the phone is selected. If the hearing instrument also contains a telecoil, PhoneNow can be programmed to switch to inductive transmission of the phone signal through the telecoil. Regardless of the presence or absence of a telecoil in the hearing instrument, PhoneNow is activated through a small magnet that is affixed to the phone receiver.
TwinPhoneTwinPhoneTwinPhone is the optimal solution for these wearers. It is automatically activated by a magnetic signal, so the wearer hears the caller in both ears for better understanding.

DirectionalityDirectionalityDepending on the types and number of microphones a hearing aid has, the hearing aid may be able to boost sounds from specific directions (by reducing sounds from other directions). This can be helpful to focus on a speaker directly in front of the hearing aid user, as well as to give the user information about where different sounds are coming from.
MultiScope Adaptive Directionality™MultiScope Adaptive Directionality™Allows the hearing care professional to set how wide the directional beam should be for each individual user.Natural Directionality™ IINatural Directionality™ IINatural Directionality II provides the listener with the benefits of both omnidirectional and directional modes simultaneously. This option eliminates the need for manual or automatic switching between omnidirectional and directional modes, as both modes are always available to the listener.SoftSwitching™SoftSwitching™SoftSwitching uses sound level and speech detection algorithms to decide when directionality is likely to be advantageous in a certain listening environment. It also offers the same four selections of MultiScope beamwidth settings: the default AutoScope, Narrow, Medium and Wide. The SoftSwitching mode differs from MultiScope Adaptive Directionality in that it uses slower transitions between directional settings and the omnidirectional setting, which is sometimes more comfortable and preferable among certain hearing aid users.Synchronized SoftSwitching™Synchronized SoftSwitching™SoftSwitching (synchronized between ears) uses sound level and speech detection algorithms to decide when directionality is likely to be advantageous in a certain listening environment. It also offers the same four selections of MultiScope beamwidth settings: the default AutoScope, Narrow, Medium and Wide. The SoftSwitching mode differs from MultiScope Adaptive Directionality in that it uses slower transitions between directional settings and the omnidirectional setting, which is sometimes more comfortable and preferable among certain hearing aid users.
Narrow DirectionalityNarrow DirectionalityNarrow Directionality uses binaural processing of the audio signal to deliver scientifically proven speech understanding benefits in noise. Coupled with HD Spatial, the wearer will experience improved signal to noise ratio and a transparent and natural sound experience.

Environmental AdaptationEnvironmental AdaptationThe hearing aid can detect different acoustical environments, like speech in noise, and adjust the sound of the hearing aid accordingly to drive comfort or speech understanding, etc.
Environmental ClassifierEnvironmental ClassifierThe Environmental Classifier is the basis for precise noise reduction and exceptionally comfortable transitions between listening environments. It’s the only hearing aid system that analyzes patterns of energy to distinguish speech from other sounds.
3D Classifier: 5/53D ClassifierUnlike conventional classification systems which rely on acoustic data, 3D Classifier analyzes multidimensional information from the wearer’s environment and communication behavior. Information on the wearer’s voice activity, motion state, and acoustic data are used to tailor the hearing aid’s response to the wearer’s needs.

Feedback SuppressionFeedback SuppressionIf any sound amplified by the hearing aid escapes the ear canal, it may reach the hearing aid’s own microphone and cause a harsh whistling noise. Some hearing aids are able to recognize when this feedback occurs and reduce or eliminate it.
Auto DFS™Auto DFS™Auto DFS also consists of two cancellation filters; one is slow-adapting the other is fast-adapting. The fast-adapting filter estimates the feedback path for a few seconds every time the hearing aid is turned on. This updates the slow-acting filter, which then continues to monitor the feedback path based on the estimation of the fast-acting filter. When the hearing aid is turned off, the slow-adapting filter stores the estimation obtained over the course of the weartime. When the hearing aid is turned on again, the slow-acting filter has a more accurate “picture” of the feedback path in that particular ear than it did in the previous use.DFS Ultra™ IIDFS Ultra™ IIDFS Ultra II analyzes and models the incoming sound and uses this information to prevent the feedback cancellation filters from attacking desired sounds. This results in excellent feedback cancellation performance without creating disturbing sound quality artifacts.Music Mode™Music Mode™The Music Mode feature in DFS Ultra II controls feedback while maintaining a more accurate representation of music. It provides excellent sound quality without tonal artifacts for hearing aid users who enjoy or play music, giving users a clearer, richer distortion-free music experience.

Noise ReductionNoise ReductionThis feature uses modern hearing aids’ processing power to examine the incoming sound signal, determine if noise is present and reduce the volume of the troublesome sound to increase comfort.
NoiseTracker™ II: On/OffNoiseTracker™ IINoiseTracker II uses a technology called spectral subtraction. Spectral subtraction works by subtracting the short-term noise spectrum from the signal, leaving only the speech portion behind ... ReSound’s NoiseTracker II is able to use spectral subtraction successfully because the Environmental Classifier has identified speech and noise so precisely.

Phone Ear FocusPhone Ear FocusWhen on a phone call, some hearing aids can focus amplification on the phone ear and reduce amplification in the non-phone ear.
Comfort Phone™Comfort Phone™Comfort Phone utilizes the bilateral wireless synchronization between hearing instruments to identify the “phone ear” and the “non-phone ear.” The amplification for the non-phone ear is then attenuated by 6 dB.

Wind Noise ReductionWind Noise ReductionAs wind blows against the microphones of hearing aids, unpleasant noise may be generated. Some hearing aids have the ability to recognize this wind noise and reduce its level. Such reductions may also affect the audibility of desired sounds, like speech.
Wind Guard: On/OffWind GuardWhen no wind noise is found, the hearing aid constantly updates and stores the sound input levels in each Warp band. Then, when wind is present, WindGuard calculates the amount of gain reduction needed to return to the stored level of the specific bands affected by wind noise.
