Abstract
A hearing protection device configured to measure the noise exposure of a user and to provide a time remaining estimate until a maximum noise exposure level is achieved. Generally, the hearing protection device may comprise a sound sealing section, a microphone configured to generate a detected sound signal indicative of the measured sound level at the user's ear canal, a memory/storage configured to record the detected sound signal as sound exposure history, a timer configured to measure the amount of time the hearing protection device is exposed to sound, and a processor configured to receive a timer signal from the timer and the detected sound signal to calculate a time remaining estimate until reaching the maximum noise exposure level. Additionally, the maximum noise exposure level may be based on industry regulations or personalized hearing thresholds.
