At Custom Protect Ear we care about your hearing health and the responsibility of teaching and practicing good hearing health. So to do so, we have provided you with some hearing conservation programs tips which may help you when creating your own.


HEARING CONSERVATION (Standards & Programs)

CSA Z94.2 Standard: Hearing Protection Devices — Performance, Selection, Care, and Use

This is the seventh edition of CSA Z94.2, Hearing protection devices – Performance, selection, care, and use. It supersedes previous editions published in 2002, 1994, 1984, 1979, 1974, and 1965.

This edition expands on performance requirements and the rating schemes that might help the user select hearing protection devices. It now includes the widely used noise reduction rating (NRR) and an applicable derating scheme.

This edition no longer includes physical performance and related testing requirements (such performance is no longer sought by Canadian users). It addresses acoustical performance measurements and includes revisions in the packaging marking requirements to clarify the use of the various ratings.

This new version of the standard meshes more closely with US approaches, recognizing the reality of how closely our two economies are entwined and provides more guidance to health and safety professionals needing reliable information on how to select hearing protection. It should become the new standard for due diligence in selecting and using hearing protection in Canada.

What is a Hearing Conservation Program?

An effective occupational HCP preserves and protects the hearing of employees who work in manufacturing, farms, mines, military bases and other noisy workplaces. An HCP also gives employees the knowledge they need to protect themselves from nonoccupational noise exposure.

According to OSHA, an occupational HCP consists of these elements:

  • Noise measurement
  • Noise control
  • Audiometric testing
  • Hearing protection
  • Employee education and training
  • Record keeping

While OSHA provides the minimum standards for hearing conservation, the National Institute of Occupational Safety and Health provides a practical guide outlining the 8 components of an HCP that are con­sidered to be best practices:

  • Noise exposure monitoring
  • Engineering and administrative controls
  • Audiometric evaluation
  • Use of hearing protection devices
  • Education and motivation
  • Record keeping
  • Program evaluation
  • The HCP audit

National Hearing Conservation Association (NHCA)   

The mission of the NHCA is to prevent hearing loss due to noise and other environmental factors in all sectors of society.

NIOSH – National Institute for Occupational Safety and Health

NIOSH provides national and world leadership to prevent work-related illness, injury, disability, and death by gathering information, conducting scientific research, and translating the knowledge gained into products and services, including scientific information products, training videos, and recommendations for improving safety and health in the workplace.

NIOSH researchers initiated a new effort to collect data published by manufacturers of hearing protectors.

Program Evaluation Checklist
Failures or deficiencies in hearing conservation programs can often be traced to inadequacies in the training and education

Hearing Conservation Products

Hearing Protectors 

dB Blockers™ are custom fit to each individual wearer for maximum comfort and are made from SkinsoftT medical silicone. dB Blockers™ are particularly suited for industrial applications where communication between individuals is desired.

Communication Devices

Miscommunication triggers accidents. With dB Com™, you can avoid mishaps and dangerous situations, and eliminate any chance of misunderstandings on the floor. Our wide selection of hearing protectors connects to numerous communication devices, so your workers can hear and be heard while staying completely protected.

Fit Check Testing 

Developed by NIOSH and distributed by CPE and ProtectEar USA, FitCheck Solo™ is fast, accurate and simple 

FitCheck Solo™ helps take the guess work out of matching the correct hearing protection with known noise exposure. It’s the only system that can test the actual plug a person is wearing without having having them first remove them. That’s what makes it the most accurate system currently available.
