According to researchers at the University of Colorado Boulder, nursing home residents enjoy music more if their hearing aids are adjusted before it's played.
The researchers found that current hearing aid technology makes it easier to follow conversations, but distorts music. These hearing aids use a technology called wide dynamic range compression, which boosts softer sounds while providing less amplification to loud sounds. This technology isn't ideally suited for listening to music, which commonly uses multiple volume levels during a single song. Instead, a hearing aid that boosts volume across the board is a better fit.
Many modern hearing aids can be adjusted to perform this way (it's actually the way many older models functioned). The key is that clinicians know to make the adjustment before residents listen to music.
