The purpose of an audiometry exam for hearing loss is first to determine if you indeed have a hearing impairment and then how severe or subtle it is. An audiometry exam will also help determine the hearing impairment you have: sensorineural, conductive or mixed. Conductive refers to any loss of hearing in one or both ears; sensorineural is caused by damage to the middle ear, which provides sound waves and nerve impulses to the inner ear; mixed is a combination of the two. Most audiologists can use a variety of audiometry techniques to evaluate your hearing. These include audiometry with an otoplasty (to lift the eardrum), audiometry with an instrument called a tympanum, or audiometry with an audiometry device such as a hearing aid.

With an audiogram, your audiologist will generate a series of sounds that you hear normally; these will then be played for you. Each time a sound is played, your audiologist will measure the frequency, amplitude, and sound level. Your audiologist is expected to be skilled enough in his or her job to play all the sounds at exactly the right volume. He or she may vary the level of each sound by using varying levels of amplification. Once all the sounds are recorded, your audiologist will play them back for you.
Some audiometry equipment is more complex than just playing back noises. During audiometry, your audiologist may use a computer, keyboard, and headphones. The computer will provide cues about the types of sounds you hear, and the headphones will serve as a device to cancel out other sounds in your environment. The computer is particularly useful when your hearing test Adelaide are performed while you’re lying down; by displaying thousands of different types of sounds, it helps you locate the one that most closely resembles what you’re hearing. Also, the computer can store data about the types of noises you’ve heard before so that you’ll remember them during future appointments.
Many people assume that when they or someone they love has a hearing test Adelaide, the hearing loss has already been corrected. Unfortunately, not all cases of hearing loss are reversible. There are several different types of hearing aids on the market today. These hearing aids are usually calibrated to a specific frequency range. When you or your loved one has a hearing test, your audiologist will determine which hearing aid is best suited to your specific needs. Some hearing aids are suitable for all situations, and others are designed for particular situations.
Suppose you or your loved one has experienced hearing loss because of hearing damage caused by exposure to loud noises. In that case, you might be surprised to learn that audiometry is not the only diagnostic tool available. Several things can cause hearing problems. Exposure to loud noises, such as rock concerts, can damage your hearing. However, some things cause hearing damage even when no sound is present. For this reason, you should have your hearing health regularly evaluated to ensure that no hearing issues are currently hindering your quality of life.
The importance of visiting a hearing test centre can’t be overstated. In the age of MP3s and digital wireless headphones, it’s difficult for anyone to avoid hearing tests. In particular, people living in environments where noise levels are extremely high will experience hearing damage over time without ever being exposed to high-volume music or noisy environments. Fortunately, there are hearing test Adelaide available that can pinpoint exactly what type of noise you’re exposed to daily. For example, if you’re listening to music at work in your car on a highway, you’ll probably find that the volume level isn’t too distracting. However, if you’re at a party with people screaming over one another, the volume can become a problem.
