REAL-WORLD SOUND IN REAL TIME
TruSound technology helps to perfectly replicate and reproduce all the world’s sounds – allowing users to adapt to everything from speech to nature to conversation and music.
Evidence suggests that hearing aid users prefer sound quality generated by a slow-acting compression system. But sometimes, slow-acting compressors aren’t enough. That’s why we developed TruSound Stabilisers.
TruSound stabilisers help preserve the high sound quality expected from the TruSound compression system – even in demanding situations. Stabilisers are designed to handle quick changes in sound environments, preventing smearing of the signals’ temporal and spectral contrast.
Sudden changes in loudness
Loud noises do not have the same amount of gain as applied to quiet environments. When sound levels increase rapidly, hearing aids must react quickly to these changes – like when a user leaves a crowded room to answer a phone call. TruSound Stabilisers help even out the sound peaks so that sound is never too loud for the user.
A study by Keidser et al. (2009) showed that transient sounds are often perceived as more annoying to hearing aid users than non-users. With TruSound softener, we minimize the irritation caused by these sounds without completely removing them.
Transient sounds come in all sound levels:
- Soft transient sounds include computer keystrokes and ticking clocks
- Medium transient sounds include clanging dishes and clattering cutlery
- Loud transient sounds include fireworks and hammer blows.
Loud transient sounds are less than one second long and rise to their peak loudness quickly. They often exceed the hearing aid user’s comfort level if the gain is not reduced. Soft and medium levels, however, need that gain to be able to be heard. With TruSound softener, all transient noise sounds can be identified and handled efficiently without affecting speech sounds.
Soft sounds should be audible, speech should be intelligible, and loud sounds should be comfortable for hearing aid users. The TruSound softener helps accomplish this by reducing gain relative to the user’s hearing loss to provide a comfortable and realistic rendition of any sound environment.
