标准摘要
[中文适用范围]： 本国际标准规定了确定听觉信号声压级范围的方法，以便消费产品的用户，包括患有年龄相关性听力损失的人，能够在存在干扰声音的情况下正确听到信号。 本国际标准中的听觉信号是指具有固定频率的声音（也称为嘟嘟声），不包括变频声音、旋律声音或语音指导。 本国际标准适用于在距离产品大约 4 m 的最大距离处听到的听觉信号，只要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，或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。 本国际标准没有规定其他法规所规定的听觉信号的声压级，例如火警、煤气泄漏和预防犯罪的听觉信号，也没有规定电话等通信工具特有的听觉信号。 本国际标准未规定 ISO 7731、ISO 8201 和 ISO 11429 涵盖的公共或工作区域的听觉危险信号。 [外文原描述]： 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.
