What machine is used for hearing screening?
An audiometer is a subjective device that is used to evaluate the hearing threshold of a person.
What is portable audiometer?
In the late 1950’s portable audiometers were developed as an effort to reach populations without access to hearing tests conducted in controlled environments by highly trained professionals. At their least impressive, is a stripped down tabletop audiometer with a handle attached.

How do you perform a hearing screening with an audiometer?
Same Ear Hearing Level Procedure
- Obtain a threshold screening on the better ear with the right (red) headphone and record the results.
- Obtain a threshold on the same ear with the left (blue) headphone and record the results.
- Check thresholds at each frequency to see that they differ by no more than ± 5dB.
How do you do audio screening with an audiometer?
Position the child so they cannot see the front of the audiometer. Lay headphones on the table, facing the child, set audiometer to 2000 Hz and maximum volume, and have the child practice raising either hand when a tone is heard. Perform a visual inspection of the ears.

What is audiometry screening?
An audiometry exam tests your ability to hear sounds. Sounds vary, based on their loudness (intensity) and the speed of sound wave vibrations (tone). Hearing occurs when sound waves stimulate the nerves of the inner ear.
How accurate are at home hearing tests?
While completing a hearing test in the convenience of your own home may be an attractive alternative to making an appointment with an audiologist, online hearing tests are unlikely to accurately or reliably identify the extent of your hearing problems.
How accurate is an online hearing test?
The test measures the quietest sound you can reliably hear at least 50 percent of the time — the threshold. This important data, however, only scratches the surface. It doesn’t explain how well you hear speech, how well you understand it, or whether the hearing loss is due to an injury in your ear.
What does HTL mean on a hearing test?
pure tone audiogram. A hearing test (audiometry) measures the quietest sound and individual can hear, at least 50% of the time – known as hearing threshold level (HTL).
