Occupational Noise Measurement
Precise Noise Measurement
Sound level meters comply with the IEC 61672-1:2013 Category 1 standards and can be used to measure noise exposure indicators such as EA, LAE, and LCpeak.
8-hour monitoring
An 8-hour monitoring of the workplace for EA, LAE, and other acoustic indicators was conducted to assess acoustic exposure levels against OSHA’s permitted occupational noise exposure limits of 85 dB for an 8-hour workday.
Data Recording
Equipped with data recording capabilities, it is possible to track changes in noise levels over the long term and assess the effectiveness of noise control measures.
