本文的目的是研究在经常遭受次声和稳态低频噪声作用下的压榨车间工人听觉和前庭功能的状态,并提出预防措施。次声变化用次声计测量,该仪器能记录0.3到100赫、50到140分贝声压级的次声,应用阻尼器时可测到170分贝。若与音频分析器联接还能测次声的频谱。噪声则用噪声计和倍频程滤波器记录。接受此项研究者包括各种年龄和工龄长短不等的食品工业工人共436名,其中男性383人,女性53人。第一组共216人,均为压榨机车间工人,他们在6～6(1/2)小时的工作时期内除接触总声级84～97分贝(A)的稳态噪声
The purpose of this paper is to study the auditory and vestibular function of workers in crushers under the constant infrasound and steady-state low-frequency noise and to propose precautionary measures. Infrasound changes with infrasound measurements, the instrument can record 0.3 to 100 Hz, 50 to 140 dB sound pressure level infrasound, the application of the damper can be measured to 170 dB. If the connection with the audio analyzer can also measure infrasound spectrum. Noise is recorded by the noise meter and octave filter. The researchers, who enrolled 436 food industry workers of varying lengths and lengths, comprised 383 males and 53 females. In the first group, a total of 216 people, all of whom are press shop workers, have steady-state noise of 84-97 decibels (A) during the 6 to 6 (1/2) hour working hours,
