A hearing test provides a measurement of the sensibility of a person’s hearing across the full range of speech. This test will measure in the quiet, sound- treated room that can be heard multiple points across the speech range.

They look into your ears to ensure there is no any blockage (wax) or any other reason the hearing test cannot be performed.

Hearing test results

Your Sound is measured in two ways:

➣ Volume: Measured in decibels (dB)

➣pitch: Measured in hertz (Hz)

The audiologist try to probably refer these two things when they are explained the results of your hearing test with you. If you want to a copy of the test, it is best to ask on the day.


Hearing tests are mostly carried out in a quiet environment where is sound damped from external noise. The patients who have hearing problem, they are tested through listening the sounds transmitted by an audiologist.


This audiology test, testing is done by headphone. They call this test ‘air conduction thresholds’ there sound must travel through the air of the ear canal to be heard. This process allows the audiologist to test the full hearing system. Hearing can be tested using a bone conductor device. This device that rests on the bone behind the ear. This bone conductor transmits sound vibrations by the bones of the skull directly to the inner ear. This process allows the audiologist for test the hearing of the inner ear.

Speech banana

This is a useful way to look at the audiogram through chart of ‘speech banana’ like on it. This Speech banana test is so called because of their shape as banana. This test represents the level and intensity or tone and frequency of sounds of speech in language, which when placed on the audiogram, forms a banana like shape.

Hearing tests for children:

Newborn hearing screenings: A newborn hearing screening is order across all 50 states, requiring that test in newborn babies have their hearing screened before leaving the hospital. baby having a hearing screening There are two types of newborn hearing screenings tests, both are painless and it can be done while the babies sleeps:

✅ Otoacoustic emission (OAE) screening:  This test records tiny sounds that the inner ear makes in response to clicks or chirps. That are delivered through a small, and flexible plug placed in the infant’s ear. This screening is done on each ear and a passing result confirms that the infant’s inner ears are receiving sounds or not.

✅ Automated auditory brainstem response (ABR): This test records the activity of the auditory nerve in response to clicks or chirps, delivered through a small, and flexible plug placed in the infant’s ear. This screening is a more complete test of the auditory system. It requires small electrodes to be taped to the baby’s scalp. This test is again done for each ear and a passing result confirms that the infant’s brain is receiving sounds or not.

Some number of infants fail their first hearing screening test due to fluid that may still be present in the ear canal right after birth. If an infant does not pass the initial hearing screening, schedule a follow-up screening with a pediatric audiologist within a couple of weeks. The most of infants will pass the second screening quite easily. Those who do not pass the second newborn screening, a diagnostic of hearing test from your pediatric audiologist will investigate further. When the child hears the sound and looks toward it, he/she is efforts with a visual increased toy like a flashing light or dancing bear. The infant usually stay engaged long enough for the audiologist to get a good indication of hearing ability for the better hearing ear. Around the age of two, social praise is working for behavioral testing. A pediatric audiologist use a method of testing called play audiometry for toddlers and preschool children. Play audiometry is a hearing test that is made into a game for toddlers. The parent or assistant sit on the floor in the both with the child and train them to respond to any sound they hear by doing a certain task, like putting a section in a bucket.
