Noise Dosimeters and Sound Level Meters

There are multiple methods at your disposable to mitigate the hearing loss risk, including engineering controls, administrative controls, and implementing a hearing protection program. But in order for the program to be effective and efficient, consistent monitoring of personal and ambient noise exposures is necessary to log data and determine appropriate corrective action.

TSI’s Quest™ Sound Level Meters and Noise Dosimeters provide professionals with comprehensive information on noise sources and worker noise exposure to make informed safety decisions.

Comprehensive Solutions for Occupational Noise Monitoring

In industrial settings—from manufacturing plants and construction sites to mining operations—excessive noise is a pervasive hazard. Without proper management, prolonged exposure to high decibel levels can lead to permanent hearing damage for the workforce. An effective hearing conservation program relies on accurate data to identify problem areas and validate the effectiveness of noise controls. TSI’s portfolio of noise monitoring instrumentation, featuring trusted Quest™ and Casella™ technology, provides the robust tools necessary for these critical assessments.

The Role of Sound Level Meters

Sound Level Meters (SLMs) are typically the first line of defense in noise assessment. They are designed to measure sound pressure levels in a specific area at a specific moment in time. Safety professionals use SLMs to conduct noise surveys, creating "noise maps" of a facility to identify high-risk zones. By pinpointing machinery or processes that exceed safe thresholds, organizations can prioritize engineering controls to help reduce noise at the source. Our range of SLMs offers varying levels of precision, from general survey meters to integrating class 1 meters suitable for detailed environmental and occupational analysis.

The Importance of Noise Dosimetry

While SLMs measure area noise, Noise Dosimeters are essential for understanding the personal noise exposure of an individual worker. Because workers often move between different zones with varying noise levels throughout a shift, a static measurement may not capture their total dosage. TSI’s wearable noise dosimeters are compact, cable-free, and designed to be worn on the shoulder near the ear. They log noise data throughout the workday, calculating the time-weighted average (TWA) exposure. This data is vital for determining if specific employees require hearing protection or if administrative controls, such as shift rotations, are necessary to help avoid overexposure.

Data-Driven Decision Making

Collecting data is only half the battle; analyzing it is where the value lies. TSI’s noise monitoring solutions are compatible with powerful detection management software. This allows you to download, chart, and analyze exposure data effortlessly. By visualizing the data, you can easily generate reports to share with management or regulatory bodies, helping to demonstrate due diligence and support your compliance with standards such as OSHA, MSHA, ACGIH, and ISO. With intuitive interfaces and rugged designs, TSI helps streamline the complex task of noise monitoring, enabling you to focus on implementing effective safety strategies.
