Do you need a hearing screening?

456d3d680eaacecb24a5494f05a14564-3During the month of May, the American Speech-Language-Hearing Association (ASHA) celebrated Better Hearing & Speech Month to raise awareness for hearing screenings and the treatment of communication disorders. A screening is an important tool for detecting hearing loss early so effective treatment can begin.

Hearing screening versus hearing test

hearing screening is a quick and painless process to determine how well you hear certain sounds. The screenings are conducted by a nurse, teacher, or audiologist. Screenings are pass or fail. A ‘pass’ means there are no signs of significant hearing loss. Its important to note that screenings don’t always diagnose mild hearing loss.

hearing test, also called a hearing evaluation, is a more detailed test of a person’s hearing. It is conducted by an audiologist. A hearing test can determine the type of hearing loss, its severity, possible causes, and how to treat it.

When do you need a hearing screening?

Hearing screenings are important for infants, children, and adults. Since our hearing can change throughout our lives, it’s important to monitor yours as a part of your overall health.

  • Newborns and infants. Newborns often have their hearing screened at birth. The ASHA recommends a newborn hearing screening before infants are 1 month old. It’s not uncommon for a newborn to fail a screening, but this doesn’t mean hearing loss is present. Infants are often referred to an audiologist for another screening before they’re 3 months old.
  • Children and adults. Children receive hearing screenings several times during their school-age years. For adults, ASHA recommends hearing screenings every 10 years until age 50.
  • Older adults. Hearing loss can happen to children but is more common as we age. ASHA recommends hearing screenings every three years after age 50.

Signs of hearing loss may include frequently asking people to repeat themselves or turning up the volume on devices, difficulty hearing in loud environments, or trouble with balance. Some research shows untreated hearing loss may even lead to dementia among older adults. If you recognize these symptoms in yourself or others, it’s time for a hearing test.

Types of hearing screenings and tests

There are several methods used to conduct a hearing screening. All are painless and fast.

  • Auditory brainstem response (ABR). ABR screenings use electrodes placed on the head to determine if the brain registers a sound. A person can rest or sleep during the screening. This method is often used for newborns.
  • Otoacoustic emissions (OAE). OAEs use a small earphone to deliver sounds and measure how they come back. No response is required from the person being tested. OAEs are also used to screen newborns.
  • Pure-tone testing. This hearing test uses headphones to deliver a beeping sound at various volumes and frequencies. The person being tested is required to respond each time they hear a beep. This method is often used to screen for hearing in older children and adults. It’s also the method typically used in schools or at doctor’s offices.

Causes of hearing loss

The World Health Organization estimates more than 430 million people worldwide require treatment for some form of hearing loss. Yet many people who could benefit from this treatment don’t receive it. Understanding if you’re at risk for hearing loss is critical to avoiding treatment delays.

The following factors may increase the risk for hearing loss:

  • Chronic ear infections. Repeated ear infections or fluid in the ear can damage hearing.
  • Complications in utero or as a newborn. Infections or lack of oxygen before or after a baby is born can lead to hearing loss.
  • Genetics. Hearing loss can be hereditary.
  • Head trauma. A traumatic brain injury can cause damage to the eardrum or inner ear.
  • Infections or diseases. Autoimmune diseases, meningitis, or viral infections can cause hearing loss.
  • Loud noises. Repeated loud noises over time, such as concerts, sports events, or headphone use can result in hearing loss.
  • Ototoxic medications. Several forms of over-the-counter and prescription medicines can lead to hearing loss if used over long periods of time. Consult a medical provider about your medications to prevent possible hearing loss.

Prevent hearing loss

Receiving a regular hearing screening is an important tool for identifying hearing loss, but taking the following steps can reduce or prevent hearing loss as well:

  • Avoid loud noises. Noise exposure is dangerous if it hurts your ears, causes muffled hearing, or requires you to raise your voice to be heard. It’s helpful to take breaks during loud events, wear earplugs, and wait at least 18 hours before further loud noise exposure.
  • Use headphones safely. When using headphones, keep the volume at 60%. Noise-canceling headphones help prevent the need to turn up the volume. For every hour of headphone use, take at least a five-minute break.
  • Use work precautions. Use hearing protection and practice hearing safety in the workplace.
