Saturation Sound Pressure Level
Also known as maximum sound output, this reflects the power of the hearing aid. Internationally, hearing aids' saturation sound pressure levels are categorized into five classes: low power, medium power, medium-large power, high power, and extra high power hearing aids. When choosing, users should select a hearing aid with different power levels based on the degree of their hearing loss.
