NIOSH HPD Well-Fit™: The Future is Fit-Testing

For workers and others who are exposed to dangerously loud noises which cannot be reduced or eliminated, hearing protection devices (HPDs) are absolutely necessary to save their hearing.  But if HPDs are not properly selected or correctly worn, the devices may not block out enough noise and the wearer may still risk a loss of hearing.  How can a person tell if their HPDs are fit correctly?  A new development from NIOSH – HPD Well-FitTM – can quickly and inexpensively test the performance of hearing protection.  This fit testing technology is a huge advancement in efforts to save workers' hearing.
