Our guest post this week comes from HEARING Life Australia and explains the benefits and uses of different types of hearing tests. The intention is to share this with your patients to help simplify the complexities in such a way that anyone can understand.
4 Types of Hearing Tests You Should Consider
If you often find yourself asking your loved ones to repeat themselves, find it difficult to follow conversations, or receive frequent complaints that you talk too loudly, it may be time to book a hearing test at your local hearing clinic.
Hearing tests employ a range of technologies that can determine your level of hearing impairment and whether you need to invest in a hearing aid. But with so many hearing tests available, it’s important to know which one is right for you.
Consider the following types of hearing tests:
1. Pure-Tone Testing
This hearing test will reveal the faintest tones a person can hear at various frequencies, from low to high. This test involves an audiometer machine emitting a range of beeps and whistles, called pure tones, with the participant responding to each sound.
When taking the pure-tone test, the participant may be asked to respond to the sounds through raising a finger or hand, pressing a button, or vocally affirming to indicate that a sound was heard.
The results of the test are plotted on an audiogram, a graph that charts the degree and type of hearing loss.
Pure-tone testing is a behavioral measurement that relies on patient reaction, and therefore is best performed on adults and children mature enough to cooperate with the test procedure.
2. Speech Discrimination Tests
These tests involve an audiologist assessing the participants’ ability to hear speech, with the results also recorded on an audiogram. These tests may involve the participant having to repeat words that are said to them.
Hearing loss that comes with aging generally begins with individuals losing the ability to hear higher frequencies, so that certain speech sounds begin to sound confusingly similar. A speech test can measure the amount of experienced speech distortion.
In order to assess the participants ability to understand speech with background noise, speech testing may be conducted in a quiet or noisy environment. This test is typically used on older children and adults, and may be used to confirm the results of the pure-tone test.
3. Auditory Brain Stem Response (ABR)
The ABR test provides information about the inner ear (cochlea) and the brain pathways required for hearing. For this test, electrodes are connected to the head in order to monitor the brain’s response to sounds. The participant lays still or even sleeps during the test.
This test can be performed on children, or those that might have difficulty with more typical behavioural methods of hearing loss tests.
4. Online Hearing Tests
For an initial assessment at home, taking an online hearing test is a great way find out whether someone should seek further professional assistance. While an online hearing test is not intended to replace a hearing assessment with an experienced hearing care professional, it may assist in identifying whether hearing loss is an issue.
In order to undertake an online hearing test at home, it is necessary to have Internet access with the ability to stream sounds, as well as a pair of headphones. Before starting, it is important to check that the computer volume is on and that the surrounding environment is quiet.
Online hearing tests may consist of different components, such as an audio screening which will test the respondents’ ability to hear sounds. An online test may also include questions that require honest answers regarding the person’s hearing ability. These tests will typically generate a score or recommendation that can be used as the starting point to assessing hearing health.
