Earhealth monitoring system and method III |
摘要 |
A system for monitoring sound pressure levels at the ear includes an ambient sound microphone (ASM) for receiving ambient sounds and an ear canal receiver (ECR) for producing audio signals as a function of ambient sound received at the ambient sound microphone and a sound signal received from an associated personal audio device. A logic circuit is operatively associated with the ASM and ECR and calculates a total SPL_Dose experienced by the ear for periods &Dgr;t. The logic circuit may select an action parameter in response to the Total SPL_Dose. |
