Case Studies

There are many challenges in managing occupational Hearing Conservation Programs: Fit, Selection, Protection, and Motivation. Environment may also be a major factor, such as at Shaw Industries Group, Inc., the world’s largest carpet manufacturer and a leading floor covering provider.

Although Shaw has invested in engineering and administrative controls to reduce noise levels, and continues to look for ways to decrease the exposure in the work environment, hearing protection is still needed for all workers. In fact, the company required a policy of dual protection for all its employees exposed to high noise levels.

INSPEC International Limited was commissioned by Howard Leight Hearing Protection Ltd to offer an opinion in regards to the VeriPRO system. The system is designed to provide on site training for people in industry in the selection and fitting of the most suitable ear-plug type in order to achieve the appropriate level of personal protection.


Safety professionals have a universal challenge in protecting the hearing of their noise-exposed employees: how much protection do their employees actually achieve with their ear plugs?

In this new white paper, we explore how ear plug fit testing can determine if a worker has optimal real-world attenuation for their noise environment, a critical measure of success in an occupational hearing conservation program.


Experts realize that most foam ear plug users do not properly fit their ear plugs and often compromise hearing protection for personal comfort. Meanwhile, hybrid push-in style ear plugs combine foam with an insertion aid, such as a stem, to eliminate the need for roll-down and provide a quicker, easier fit. 

Our new case study titled “QuietDose In-Ear Dosimetry is a ‘Foundational Element’ of Dixie Industries’ Safety Program” details how the Chattanooga, Tennessee, specialty forging and assembly operations company, was able to use new QuietDose in-ear dosimetry to break that cycle and abate an OSHA citation.

US Airways merges two best practice programs into one, unified Hearing Conservation Program.

In the world of personal protective equipment, bad assumptions are hazardous and can result in injury — or worse. Some persistent bad assumptions are very widespread in Hearing Conservation Programs (HCPs). Here are six of the most common bad assumptions about hearing protection for noise-exposed workers.

Discover how Howard Leight’s new VeriPRO earplug fit-testing technology now makes it possible for Nucor Steel to ensure that their employees are getting the most out of their hearing protectors.
