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
サイレントスタート
補聴器に電池を入れた後、6秒後に電源が入ります。この間に補聴器を耳にしっかり装着することで、不快なハウリング（ピーピー音）を防ぐ効果があります。
自動音量調整機能
ノンリニア機能。聴き取りにくい小さな音は大きく増幅、掃除機や洗濯機などによる大きな音は増幅を抑制します。小さな音をより明朗に、大きな音はより柔らかく自動で調整します。
大音量制御機能
デジタル処理により、補聴器から出る音を適切な水準に自動制御します。大きな音を聴いたときに従来のアナログ式補聴器で発生していた音のひずみを抑え、自然な音を実現します。
電池交換時期をお知らせ
電池の容量がなくなってくると定期的に「プーッ プーッ」と音でお知らせします。
耳あか防止フィルター付き
補聴器本体に付属する耳あか防止フィルターが、耳あかの侵入を防ぎます。
