ISO 24501:2010规定了确定听觉信号声压级范围的方法，以便消费者产品的用户，包括年龄相关听力损失的人，能够在存在干扰声音的情况下正确听到信号。 在ISO 24501:2010中，听觉信号指的是固定频率的声音（也称为哔哔声），不包括变频声音、旋律声音或语音指南。 ISO 24501:2010适用于在距离产品约4米的最大距离听到的听觉信号，前提是产品和用户之间不存在物理障碍。 它不适用于通过头部接收器或耳机听到的听觉信号，也不适用于由于头部对声音传播的干扰而使耳朵非常靠近声源听到的听觉信号。 ISO 24501:2010未规定其他法规（如火灾报警、气体泄漏和犯罪预防法规）规定的听觉信号的声压级，也未规定电话等通信工具的特定听觉信号。 ISO 24501: 2010年未规定ISO 7731、ISO 8201和ISO 11429所涵盖的公共或工作区域的听觉危险信号。

ISO 24501:2010 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 ISO 24501:2010, refer to sounds with a fixed frequency (also called beep sounds) and do not include variable frequency sounds, melodic sounds, or voice guides. ISO 24501:2010 is applicable to auditory signals which are heard at an approximate maximum distance of 4 m from the product, as long as no physical barrier exists between the product and the user. It is not applicable to auditory signals heard through a head receiver or earphones, or to those heard with the ear located very near to the sound source because of the interference of the head with sound propagation. ISO 24501:2010 does not specify the sound pressure level of auditory signals regulated by other statutes, such as those for fire alarms, gas leakages and crime prevention, nor does it specify auditory signals particular to a communication tool such as telephones. ISO 24501:2010 does not specify auditory danger signals for public or work areas which are covered in ISO 7731, ISO 8201, and ISO 11429.
