  • The Signal&Images Lab of the ISTI-CNR in Pisa has worked for many years in the field of audio-musical signals, including research on analyzing and synthesizing sounds and applications related to multimedia production and performance. One of the topics studied concerns developing methods for improving quality and fidelity when listening to music in certain specific situations. This article presents our design for an audio device to enhance music listening for the hearing impaired, as compared to commercial hearing aids. It is well known that the performance of modern hearing aids is optimized to compensate for loss within spoken audio range (4 to 5 kHz). This limit was adopted in order to avoid major complications due to miniaturization, high power consumption, and so forth. Our proposal concerns the design of a portable (not miniaturized) device based on a DSP, which implements adapted gain curves extended through the entire audio band (16 kHz). The apparatus receives incoming music from any \"line out,\" is powered by rechargeable batteries, and produces sufficient audio power to drive normal headphones, thus avoiding the need for hearing-aid earmolds. The device is especially suited to hypoacusic people with mild-to-moderate hearing loss and sufficient residual hearing in higher frequencies, especially for preverbal-age hypoacusic children. This paper discusses our preliminary experiments, describes the prototype's design characteristics, and illustrates several tests. (literal)
