We offer three different levels of Occupational Noise Surveys:
Basic Survey:
Provides average Spot Noise measurements (sound mapping) at specific positions/areas within the facility. Includes a baseline report. Typically takes about 2-3 hours, depending on how many departments there are to be tested. This is a basic average and is not an accurate indicator of what noise levels employees are exposed to.
Comprehensive Survey:
To achieve an accurate noise level survey, it is important that employees are monitored with dosimeters over at least one full 8-hour shift to get a time-weighted Lex measurement. This Lex measurement is what dictates appropriate hearing protection and if further consideration should be taken in creating a formal Hearing Conservation Program within the facility. The Comprehensive Survey includes 2 hours of Spot Noise Testing (sound mapping), Lex measurements by monitoring noise dosimeters, and a full Occupational Noise Survey Report with data analysis consultation. The average testing period is between 2-3 days, depending on the size of the facility, and how many employees or departments need to be tested.
Premium Survey:
The Premium Survey includes the same testing as in the Comprehensive package (2 hours of Spot Noise Testing (sound mapping) to provide a basic average, as well as time-weighted Lex measurements), but also provides Real-time Frequency Spectral Analysis which outlines which frequencies and SPL levels are affecting each department. The comprehensive Occupational Noise Survey Report provides data analysis consultation, and includes frequency graphs that detail which frequencies are emphasized in order to assist in designing or implementing source noise controls in an area or around equipment. Includes 3 employees being fit with noise dosimeters. The average testing period is between 2-3 days, depending on the size of the facility, and how many employees or departments need to be tested.
