Ergonomics. Accessible design. Sound pressure levels of auditory signals for consumer products LONG_TITLE BS EN 755-9 applies to1 Scope This International Standard specifies methods for determining the sound pressure level range of auditory signals so that the users of consumer products, including people with age related hearing loss, can hear the signal properly in the presence of interfering sounds. Auditory signals, in this International Standard, refer to sounds with a fixed frequency (also called beep sounds) and do not include variable frequency sounds, melodic sounds,
