Abstract
A rearward sound enhancing apparatus which includes a pair of ear covers mounted on a headband. Each ear cover includes an inner compartment and outer compartment with rearward facing openings. A microphone is provided in each outer compartment, and a speaker is provided in each inner compartment. Sound received through the rearward facing opening is picked up by the microphones, amplified, and directed to the speakers. The dual compartment arrangement of the ear covers eliminates audio feedback which would otherwise occur due to the close proximity of microphones and speakers in the ear covers.
