Problems solved by technology

[0003] The purpose of the present invention is to provide a soundproof sound box, which effectively solves the problem that the performance test of the traditional electronic stethoscope is carried out directly in a secret room and the artificial ear and the artificial mouth are directly exposed in the secret room, so that even people's breathing in the secret room will be disturbed. The test brings external noise, the artificial ear and the artificial mouth interfere with each other, the test result is inaccurate, and the tester needs to be very careful to avoid noise and inconvenience to the test

Description

technical field [0001] The invention relates to a soundproof box, in particular to a soundproof box used for testing the performance of an electronic stethoscope. Background technique [0002] Traditional electronic stethoscope performance tests are carried out directly in a secret room. Although the secret room isolates the sound from the outside world, the artificial ear and artificial mouth are directly exposed to the secret room. Even human breathing in the secret room will bring external noise to the test. Noise, artificial ear and artificial mouth will also interfere with each other, resulting in inaccurate test results, and testers need to be very careful to avoid noise, which will bring inconvenience to the test. In order to overcome the above defects, we have developed a soundproof box. Contents of the invention [0003] The purpose of the present invention is to provide a soundproof sound box, which effectively solves the problem that the performance test of the...
