Psycho Acoustics Certification

The user experience of products is increasingly receiving attention from consumers. In addition to visual and tactile factors, the auditory factor also plays an important role in the user experience of household appliances. The negative experience that noise from household products brings to users has already received widespread attention in the market. Currently, the international evaluation of noise from household appliances mainly focuses on sound pressure level and A-weighted sound level. Under the same sound pressure level, the perceived impression of different types of product noise differs greatly, and different noise spectra bring completely different auditory sensations to users. Research on psychoacoustics is gradually becoming a trend in the future industry development, and targeted improvements based on sound quality directly affect user experience.

The certification series for product noise sound quality takes into account the psychological impact of different noises on users. For some unavoidable noise, the certification aims to optimize the design in a way that makes it acceptable to users and issue a certificate to guide consumer choices.
