Agenda

Agenda

  • Today’s agenda:

    • Introduction

    • Occurrence of hearing loss

    • Noise measurement

    • Hearing conservation program

    • Elements

    • Your responsibilities


Hearing loss

Section 1

Hearing Loss


Why talk about noise

Why Talk About Noise?

  • OSHA estimates approximately 30 million people are exposed to hazardous levels of noise:

    • Noise induced hearing loss is a common occupational disease

    • Second most self-reported occupational injury


Common effects of noise

Common Effects of Noise

  • Noise pollution - to constant presence of noise:

    • Exposure to high noise increases stress levels

    • Noise can make you feel tense


Some sobering statistics

Some Sobering Statistics

  • Industry specific studies have indicated that:

    • 44% carpenters reported hearing loss

    • Half the plumbers reported similar problems

  • Workers exposed to noise include:

    • Agriculture

    • Mining

    • Construction

    • Manufacturing

    • Utilities

    • Transportation

    • Military


The facts about hearing loss

The Facts About Hearing Loss

  • Hearing loss can be temporary or permanent:

    • Temporary - exposed to noise sources

    • Permanent - exposure to high noise levels

      • Permanent - cumulative process


How hearing loss occurs

How Hearing Loss Occurs

  • Ear is divided into three parts:

    • Outer Ear

      • External part of ear canal that captures sound

    • Middle Ear

      • Contains ear drum and several small bones

    • Inner Ear

      • Contains cochlea, and hair cells connected to nerves

      • Sound vibrations stimulate hair cells sending signals to the brain


Symptoms of hearing loss

Symptoms of Hearing Loss

  • Symptoms of hearing loss:

    • Can not distinguish words

    • Trouble following conversations

    • Strain to hear

    • Feel sounds being annoying or loud

    • Hearing noise in one or both ears


Measuring sound

Section 2

Measuring Sound


Sound terminology

Sound Terminology

  • Understanding terminology of noise energy:

    • Noise-created by sound pressure waves

    • Frequency of sound waves determines its pitch

    • Ear is capable of hearing vibrating sound waves

  • Intensity is a term for loud noise:

    • Higher the intensity-louder the noise

    • Noise intensities can damage your hearing

Our hearing conservation program

Section 3

Our Hearing Conservation Program


Hearing conservation program hcp

Hearing Conservation Program (HCP)

  • HCP elements:

    • Noise monitoring

    • Annual audiometric testing

    • Provision of hearing protection

    • Employee training programs

    • Recordkeeping


Exposure monitoring

Exposure Monitoring

  • Measuring noise levels:

    • Surveys are conducted

    • Retain survey documents and review periodically

    • Consider engineering and administrative controls before hearing protection


Audiometric testing

Audiometric Testing

  • Audiometric testing is test of hearing:

    • Performed in a sound booth

    • Respond to a series of tones

    • Baseline exam is performed on hire

    • Baseline exam is used for comparison


Audiometric testing1

Audiometric Testing

  • Audiometric test:

    • Threshold of hearing

      • Level when a tone becomes audible

    • Threshold shift

      • Changes in threshold of hearing

    • Standard Threshold Shift (STS)

      • Shift of 10 decibels or more in certain frequencies


Hearing protection

Hearing Protection

  • Use protection at 85 decibels or more:

    • Irritating sound in the work area

    • Raising your voice to be heard

    • Having hard time hearing someone

    • Speech sounds dull or muffled

    • Ears ring or hurt after noise exposure


Available hearing protective devices hpds

Available Hearing Protective Devices (HPDs)

  • Three basic types of protective devices:

    • Earplugs

    • Canal caps

    • Ear muffs


How hpds are rated

How HPDs are Rated

  • Hearing protection devices are:

    • Designed to block noise energy

    • Have different capabilities and applications

  • Issue regarding hearing protective device is:

    • Noise reduction rating (NRR)

    • NRR is a measurement for noise blocking devices

    • Higher NRR - better protection


Earplugs

Earplugs

  • Earplugs offers noise reduction rating (NRR):

    • Good in most temperatures and humidity

    • Formable types are inexpensive

    • Earplug can be uncomfortable

    • Get dirty when handled in dusty environments


Canal caps

Canal Caps

  • Canal caps are quick fit and compact:

    • Convenient for workers

    • Offer an NRR of 20

    • Due to re-use it must be kept clean


Ear muffs

Ear Muffs

  • Ear muffs offer maximum comfort:

    • Easy to take on and off

    • Makes cleaning and maintenance easy

    • Can be combined with earplugs


Fitting and use of hpds

Fitting and Use of HPDs

  • Hearing protective device is used a specific way:

    • Formable earplugs are used by rolling the plug

    • Custom fitted earplugs do not require rolling

    • Wear canal caps by placing pad over ear canal

    • Wear ear muffs by placing cups over ears


Care of hearing protectors

Care of Hearing Protectors

  • Hearing protective devices need:

    • To be maintained to avoid problems

    • To be discarded after each shift

    • Reusable earplugs need cleaning

    • To be stored in a secure place


Care of hearing protectors1

Care of Hearing Protectors

  • Care of hearing protectors:

    • Inspect Canal caps before use

    • Band should be evaluated


Care of hearing protectors2

Care of Hearing Protectors

  • Care of hearing protectors:

    • Ear muffs require care and maintenance

    • Replace cushions of the muffs periodically

    • Ear muff exterior should be periodically cleaned

    • Inspect ear muffs for damage before use


Employee training

Employee Training

  • HCP requires affected workers get training yearly:

    • Employees must know noise is hazardous

    • Prevent damage by wearing hearing protectors

    • By participating in audiometric testing


Recordkeeping

Recordkeeping

  • Maintain noise exposure measurement records:

    • Audiometric test results must be maintained

    • Records shall be provided upon request to:

      • Employees

      • Former employees

      • Representatives designated by the individual employee

      • OSHA
