Substantial data from previous research show that children and adults require different acoustical conditions for good understanding. For example, adults can understand the majority of speech when the audibility of the speech is reduced to 40% or 20%, but young children need 80% or 60% audibility for the same level of understanding. Also, while adults need 4 to 6 bands of vocoded speech to reach good performance levels, children need 8–12 bands. While adults experience a release from masking when signals and background noise arise from different angles, children do not gain the same benefit, and in fact may experience masking from background noises coming from any direction. J.H. and J.S. from Acentech prepared auralizations that demonstrate these differences between children and adults. Those auralizations will be presented and discussed as possible educational tools. |
