Natural sound quality and high functionality Natural and smooth sound quality OHS-D31 processes the sound into 12 divisions (OHS-D21 / EH21 into 8 divisions). The more divisions, the smoother the sound. Noise suppression The OHS-D31 uses 12 channels of digital processing (the OHS-D21 / EH21 uses 8 channels of digital processing) to separate noise and voice. This reduces the noise portion, making it easier to hear the voice even in noisy places. Howling suppression function Suppresses unpleasant beeping sounds. Quickly suppresses only howling sound without attenuating the audio through a mix of inverse phase method and frequency shift. Sound Technology (1) Suitable for a wide range of hearing abilities, from mild to moderate. Soft sounds and whispers are hard to hear. People say the TV volume is too loud. It's hard to hear normal conversation. You only notice when a car pulls up beside you. This is just a guide. Feelings will vary depending on the individual. Sound Technology Silent Start After inserting the battery into the hearing aid, it will turn on after 6 seconds. During this time, securely placing the hearing aid in your ear helps prevent unpleasant feedback (beeping sounds). Automatic volume control Non-linear function. Loud noises that are difficult to hear are amplified, while loud noises caused by vacuum cleaners, washing machines, etc. are suppressed. Loud sounds are automatically adjusted to be clearer and loud sounds to be softer. Volume control function Digital processing automatically controls the sound coming out of the hearing aid to the appropriate level. This reduces the sound distortion that occurs with conventional analog hearing aids when listening to loud sounds, resulting in a more natural sound. Notification of battery replacement time When the battery runs out of capacity, it will periodically announce this with a "beep-beep-beep" sound. Includes earwax-preventive filter An ear-dust prevention filter attached to the hearing aid body prevents ear-dust from entering the hearing aid.
