Used to locate sources of acoustic leakage, the EAR allows "before and after" comparisons to determine the effectiveness of the noise masking, and connects easily to recorders, spectrum analyzers, or other test equipment for more detailed analysis.
Easy to use, the EAR-2000 is simply placed with its contact against the surface to be tested. The internal automatic gain control and voice band response will deliver clear, undistorted sound.
The EAR-2000 will identify sources of voice leakage such as walls, windows, air ducts, plumbing, conduit, etc. The Record Output can be connected to any standard tape recorder and can also be used with Audio Spectrum Analyzers and other measurement equipment for detailed analysis.
The EAR-2000 is intended for training and test purposes only, and is not to be used in a surreptitious manner. |
