Hearing device delays

Dealing with Delay in Wireless Hearing Systems

Hearing technology has to meet strict delay requirements, but wireless protocols like Bluetooth have large delays. We can use delay-robust signal processing strategies to use the data from these wireless devices even if it's delayed.

Group Conversation Enhancement

A group conversation enhancement system turns up the voices of users in the group while tuning out background noise, for example in a crowded restaurant.

Multiple remote microphones are processed to produce a binaural output

Improving remote microphones for group conversations

Wireless remote microphones make it easier to hear by sending sound directly from the talker's mouth to the listener's ears, but they don't work well group conversations with multiple talkers. We propose an immersive system for group conversations.

Dynamic range compression maps a wide range of loudness to the narrow range of a listener

Dynamic Range Compression and Noise

Every modern hearing aid uses dynamic range compression to control loudness, but compression can cause distortion in noisy places like restaurants. We developed a mathematical model explaining these distortion effects.
