Telephone Protection Hoods Model 404

These telephone protection hoods are an excellent aid to eliminate extraneous noise and improve audibility in noisy surroundings where open telephones have to be installed for economic reasons. The special shape of the hood and its inner lining of sound-absorbing material optimally reduces noise in the area of the telephone. Eavesdropping is also made difficult. The best acoustic effect is achieved when the protection hood is mounted with its back facing the noise source or loudest noise source. The hood is made of sheet metal and lined on the inside with sound absorbing mineral fibre boards behind a perforated plate cover.
