Ultimate Noise Induced Hearing Loss Guide

Noise induced hearing loss, as its name suggests, is the result of damage from excessive exposure to harsh noise and sounds.

In this ultimate guide, we walk you through everything you need to know about the hearing impairment.

What is Noise Induced Hearing Loss?

Noise induced hearing loss (NIHL) is a common type of hearing loss. Every day, we are exposed to a variety of sounds at a variety of levels and it can be difficult to avoid certain noises on a daily basis. Often, these sounds are not damaging enough to cause us trouble, but when they become too loud, they can result in temporary and even lasting damage. The harm caused to the inner ear or ear drum could even be irreversible.

In many cases, NIHL can be categorized as sensorineural hearing loss.  This loss is permanent and requires hearing aids to effectively manage the impairment.

Causes of Noise Induced Hearing Loss

NIHL can be caused suddenly or develop over time. For example, both a spontaneous loud bang or a constant exposure to high volumes for an extensive period of time can lead to hearing loss.

This type of hearing loss can, at time, be attributed to the workplace. Many careers are not hearing-friendly such as industrial professions.

It is not just our job which can be a key cause. Noise pollution can be incredibly damaging to our ears. With detrimental effects on our health, environmental or outdoor noise damage can be dated back as far as Ancient Rome.

However, in the 21st century, some of the most popular sources of noise pollution are:

  • Rapid population growth
  • Vehicular noise from trains, planes, and even emergency services
  • Industrial or workplace noise
  • Everyday sounds

To highlight how everyday sounds impact us, it was revealed in a recent study that 91% of us would avoid revisiting a noisy restaurant.

How Does Noise Damage Hearing?

It is the damage to or even death of ear hair cells that lead to hearing loss.

When high-intensity sound enters the ear canal, it can cause trauma to the hair cells and other parts of the ear. Ultimately, this trauma damages how we hear, affecting how we perceive sound moving forward. It is this damage from high dB noise that weakens our ability to process sounds.

When Does Sound Become Harmful?

We are constantly exposed to all sorts of sounds every single day, and a lot of the time it is difficult to avoid loud noises. But, when does sound become dangerous?

Lower decibel sounds are unlikely to cause us much concern. It the sounds that exceed 85dB we need to wary of. To put that into perspective, it is estimated that sounds from busy city traffic measure around the 85dB mark. Even the sound levels from loud music can cause hearing loss or tinnitus. This is more common in musicians.

Continuous exposure to loud noise can damage our cells in the inner ear and auditory nerve, resulting in noise induced hearing loss.

Possible Symptoms of NIHL

As with any hearing impairment, symptoms may vary from person to person.

Depending on the root cause of NIHL, different signs may be present. For example, an instant loss of hearing due to noise may present different symptoms to a loss which has occurred gradually over time. Below are some indicators:

  • Muffled hearing
  • Vertigo
  • Tinnitus
  • Physiological complications such as damage to ear hair cells, inflammation or synaptic change
  • Permanent hearing loss

If you experience any of the above, it is recommended that you consult with a medical professional who could help diagnose your condition.

How To Prevent Noise Induced Hearing Loss

It can be tricky to avoid hazardous noises. Afterall, sound is everywhere. Depending on our lifestyles, some people are more likely to be at risk than others.

There are a number of precautions we can take to help reduce the risk of hearing damage:

  • Wear ear plugs when present in high-noise environments such as gigs or those above 85 dB.
  • Wear work appropriate protection if your job requires it.

  • If you cannot directly influence the volume, find a safer place that is quieter.
  • Inform others around you that an area or event could have harsh consequences on our hearing.
  • Take a test to check for hearing loss.
