Title Perception of acoustic signals when wearing hearing protectors
Original title Wahrnehmbarkeit akustischer Signale beim Tragen von Gehörschutz [in German]
Bibliographic information Dec. 1976, No.12, p.471-474. Illus.
Abstract The main arguments against the use of hearing protectors are disturbance of communication and the inability to hear acoustic signals. It is shown by reference to specific octave spectra that acoustic signals can also be masked by other noise sources. Tests in which the hearing threshold for signals in a noisy industrial environment (mine tools and machinery) or during the use of hearing protectors was determined are reported. At the usual frequencies, noise signals are heard as well or better by workers wearing hearing protectors.
