本文叙述了声压级为165—173dB的宽频带噪声场对豚鼠的生理效应。求得了在不同声压级下豚鼠致死的时间。实验表明,若声级增加3dB,豚鼠致死时间减半,并且它的噪声的致死剂量是一个常数,约为33J/mm~2。
This article describes the physiological effects of a broad band noise field with a sound pressure level of 165-173 dB on guinea pigs. Obtained at different sound pressure levels of guinea pigs died of time. Experiments show that if the sound level increased 3dB, guinea pigs lethal time by half, and its lethal dose of noise is a constant, about 33J / mm ~ 2.
