The Cadenza project aims to improve the audio quality of music for those who
have a hearing loss. This is being done through a series of signal processing
challenges, to foster better and more inclusive technologies. In the first
round, two common listening scenarios are considered: listening to music over
headphones, and with a hearing aid in a car. The first scenario is cast as a
demixing-remixing problem, where the music is decomposed into vocals, bass,
drums and other components. These can then be intelligently remixed in a
personalized way, to increase the audio quality for a person who has a hearing
loss. In the second scenario, music is coming from car loudspeakers, and the
music has to be enhanced to overcome the masking effect of the car noise. This
is done by taking into account the music, the hearing ability of the listener,
the hearing aid and the speed of the car. The audio quality of the submissions
will be evaluated using the Hearing Aid Audio Quality Index (HAAQI) for
objective assessment and by a panel of people with hearing loss for subjective
evaluation.

Cadenza 项目旨在通过一系列信号处理挑战来改善听力受损人群的音乐音质。该项目考虑了两种常见听音情景：戴耳机听音乐和在汽车中使用助听器。在这些情景下，通过将音乐分解为人声、低音、鼓和其他组成部分并进行智能重混，来个性化地提高听力受损人群的音质。另外，通过考虑音乐、听众的听力能力、助听器和汽车的速度，提升从汽车扬声器中传出的音乐以克服汽车噪音的遮盖效应。提交的音频质量将通过 Hearing Aid Audio Quality Index (HAAQI) 进行客观评估，同时由一组听力受损人员进行主观评价。

The First Cadenza Signal Processing Challenge: Improving Music for Those  With a Hearing Loss

The Cadenza project aims to enhance the audio quality of music for
individuals with hearing loss. As part of this, the project is organizing the
ICASSP SP Cadenza Challenge: Music Demixing/Remixing for Hearing Aids. The
challenge can be tackled by decomposing the music at the hearing aid
microphones into vocals, bass, drums, and other components. These can then be
intelligently remixed in a personalized manner to improve audio quality.
Alternatively, an end-to-end approach could be used. Processes need to consider
the music itself, the gain applied to each component, and the listener's
hearing loss. The submitted entries will be evaluated using the intrusive
objective metric, the Hearing Aid Audio Quality Index (HAAQI). This paper
outlines the challenge.
