发明名称 Sound pressure level monitoring and notification system
摘要 Methods of acoustic dose monitoring and acoustic dose systems are provided. An acoustic dose system includes a first device configured to measure sound pressure levels directed to an ear drum and a second device configured to convert the sound pressure levels into a sound pressure level dose. The second device sends a notification signal to a third device if the sound pressure level dose is larger than a threshold value.
