What to Expect During a Noise Dosimetry Survey

A noise dosimetry survey is a crucial process in assessing and mitigating the risks associated with noise exposure in various work environments, including flightlines, shop areas and warehouses. This article aims to provide an in-depth guide on what to expect during a noise dosimetry survey, helping individuals and organizations understand the process, its importance, and how to prepare for it. As a facility manager, business owner, or individual concerned about noise exposure, it is essential to understand the risks associated with noise exposure and the benefits of conducting a noise dosimetry survey.

The importance of noise dosimetry surveys cannot be overstated. Prolonged exposure to loud noises can lead to noise-induced hearing loss, a permanent and irreversible condition that can significantly impact an individual's quality of life. In addition, excessive noise exposure can also lead to other health problems, such as stress, anxiety, and cardiovascular disease. By conducting a noise dosimetry survey, individuals and organizations can identify areas where noise exposure is a concern and take steps to mitigate these risks.

In this article, we will provide a comprehensive guide on what to expect during a noise dosimetry survey, including the preparation process, the survey itself, and the interpretation of results. We will also discuss the benefits of conducting a noise dosimetry survey and provide resources for further information and support.

### What is a Noise Dosimetry Survey?

A noise dosimetry survey is a process used to measure and assess the level of noise exposure in a particular environment. The purpose of a noise dosimetry survey is to identify areas where noise exposure is a concern and to provide recommendations for minimizing these risks. There are two types of noise dosimetry surveys: personal dosimetry, which involves measuring the noise exposure of individual workers, and area monitoring, which involves measuring the noise levels in a particular area.

Noise dosimetry surveys are conducted using specialized equipment, called noise dosimeters. These devices must be calibrated annually and pre and post-surveys to ensure accurate and reliable data. Noise dosimetry surveys ensure compliance with noise regulations and standards. The Occupational Safety and Health Administration (OSHA) and the National Institute for Occupational Safety and Health (NIOSH) have established guidelines and regulations for noise exposure, and conducting a noise dosimetry survey can help ensure that these regulations are being met.

### Pre-Survey Preparation

Before conducting a survey, it is essential to identify the noise sources and areas of concern. This can involve conducting a preliminary assessment of the environment, including identifying potential noise sources, such as machinery, equipment, and traffic. To reduce unnecessary exposures, noise dosimetry should be scheduled during routine tasks involving noise equipment. Health and safety professionals play a critical role in preparing for a noise dosimetry survey, as they can provide valuable insights and expertise in identifying areas where noise exposure is a concern.

Only trained professionals should conduct the survey. A survey plan, which outlines the objectives, methods, and procedures for the survey, should be communicated early and often. The survey plan should also include information on the equipment and personnel being used, as well as the procedures for collecting and analyzing data.

### The Noise Dosimetry Survey Process

The noise dosimetry survey process involves several steps, including measurement, data analysis, and reporting. The measurement step involves using dosimeters to collect data on the level of noise exposure. The dosimeter will be placed on the worker for 8 hours or the duration of the noise process. Once the dosimeter is attached to the worker, they can continue their duties as they normally would. The health and safety professional will observe the worker and document the tasks performed and equipment used during the survey. Workers should know that noise dosimeters do not record conversations or voices. The data collected is in decibels only. Workers should not scream or yell into the microphone as this could damage the equipment.

The data analysis step involves analyzing the data collected to the OSHA 8hr Time Weighted Average (TWA). Specialized software is utilized to analyze the sound levels and to provide control recommendations. The health and safety professional will assess the worker observations with the software report. A report should be provided to summarize findings and detail compliance with noise regulations and standards.
