Abstract
A system and method include sensing sound on the inside of a protective seal of a hearing protection device being worn, and using a sliding window algorithm to calculate the sound to which the ear of the wearer is exposed. The method may also include sensing noise and generating sound to cancel the sensed noise within the ear of the wearer. It may also include sensing ambient sound and regenerating this sound at safe levels inside the hearing protection device in order to aid situational awareness, and it may include receiving signals that are then regenerated as audio inside the hearing protection device for communication or entertainment purposes.
Claims26
A system comprising:
- a hearing protection device;
- a first microphone coupled to the hearing protection device to sense sound between the hearing protection device and the eardrum;
- and
- a processor coupled to receive signals from the first microphone representative of the sensed sound and to calculate sound exposure to the ear of the wearer over a sliding window of time duration.
A method comprising:
- sensing sound on the inside of the protective seal of the hearing protection device when worn;
- and
- using a sliding window algorithm to calculate sound to which the ear of the wearer is exposed.
A computer readable storage device having stored instructions to cause a computer system to execute a method, the method comprising:
- sensing sound within the ear of a wearer of a hearing protection device;
- and
- using a sliding window algorithm to calculate sound to which the ear of the wearer is exposed.
