Novel hearing protection device and method and secure earbud assembly |
| abstract |
A passive level dependent hearing protection device for insertion into an ear canal is made of a flexible bladder attached to a frame and where the bladder utilizes valves to evacuate air from the ear canal. The device thereby causes transmission loss of acoustic waves wherein low frequency steady state and impact noises are attenuated but soft noises such as speech are attenuated to a lesser degree. The device incorporates a safety feature for preventing creation of too low an air pressure in the ear canal. Finally, the device may incorporate a transducer. |
