SoundFocus:基于听障人群手机音乐应用是由斯坦福大学读工程学的 Alex Selig 一位听障人士，他与卡内基梅隆大学计算机科学专业的 Varun Srinivasan 正在开发一款针对听障人士的音乐应用。SoundFocus 希望有一天做款硬件，除播放功能外，可将听力修复功能整合进来。

SoundFocus 的功能还仅限于测试听力水平，而后根据用户听力水平将播放的音乐调适到一个适合当前用户的频率。分别在高音区、中音区、低音区三个区间测出用户所能听见的最低声音，而后在播放音乐时，SoundFocus 会按该频率为用户的提供清晰、悦耳的声音体验。SoundFocus 支持从 iTunes library 及 Spotify 中导入音乐列表。其实即便没有听觉问题，SoundFocus 应用的测试功能也有利于我们保护听力。

SoundFocus lets people with hearing loss listen to music in full fidelity with an iPhone or iPod Touch. This is done by tuning the music to each person's unique hearing pattern and compensating for the sound frequencies they do not hear well.

Listen to music the way it was meant to be heard - from the lowest bass to the highest notes. SoundFocus gives people with hearing loss 20/20 hearing when listening to music on an iPhone or iPod Touch.

You can tune SoundFocus in less than a minute with a quick test that figures out which sound frequencies you do not hear well. Use the equalizer to enhance the audio even more. Choose from our equalizer presets or design your own.

We play all the music that you own and love - from your iTunes library to Spotify. We even support AirPlay so you can stream to your Apple TV and to AirPlay-enabled speakers.
