A diagnostic audiometer is an essential piece of equipment for many industries that have loud work environments. Besides the healthcare industry, many companies where people work under loud conditions employ nurses or other qualified technicians to provide regular audiometer testing.

To examine the tympanic membrane, however, a tympanometer should be used. This device provides information about the amount of fluid (if any) present in the middle ear.

There are many resources that provide training and educational information on operating a clinical audiometer or tympanometer. You can find audiometers and tympanometers education and training through:

1. An audiometer manufacturer that has training materials.

2. On-site training courses.

3. Additional training resources that include tutorials and user guides.

The best contacts and resources to help you get it done

Take training courses to learn about audiometer calibration and function

Manufacturers and health organizations both offer courses where audio technicians can learn how to use audiometer equipment. These classes go over how the device functions, but also the practical side of hearing testing. This includes working with the patients and interpreting test results.

I recommend: Alaska Federal Healthcare Action Network training classes teach attendees how to use many audio diagnostic tools, including audiometers and tympanometers. The company also offers refresher courses for those already familiar with the equipment. Gordon N. Stowe and Associates provides a class on audiometric equipment and other audiology topics.

Attend workshops to learn how to operate automatic and manual audiometer technology

Workshops are another way to get the training you need to perform hearing testing, quickly. Many state organizations hold educational workshops to prepare technicians for audio testing in schools. Workshops last anywhere from 4 to 8 hours, and are designed to be refresher courses for those who already know how to use audiometer equipment.

I recommend: The Minnesota Department of Health provides a hearing and vision screening workshop that teaches people how to use audiometer equipment for hearing testing in schools. The Mississippi Speech Language Hearing Association offers an annual conference that covers many educational topics, including instruments and technology.

Explore additional online educational resources from an audiometer manufacturer

Many manufacturers that do not provide training courses will provide some type of educational resources to learn more about the equipment they make and sell. Educational resources can include tutorials, user guides and expert support for those using tympanometric and audiometric equipment.

I recommend: Workplace Group provides an introduction to the practical use of tympanometers in workplaces outside the medical profession. Welch Allyn provides an overview and user guide for many tympanometric instruments in its technical library.

Find clinical audiometer and tympanometer sellers

The diagnostic testing equipment needed for an audiology practice can be found online, sold by companies that specialize in audiometer equipment. Browse the websites of these companies for great deals on the equipment you need to administer accurate hearing tests and make proper audiological diagnoses.

I recommend: Wilner-Greene Associates is a seller of audiometers and tympanometers and other diagnostic testing equipment. Medical Resources sells new and used audiometers, tympanometers and other equipment on its website.

Look up manufacturers of audiometers and tympanometers

When you first open your hearing care practice, sometimes buying direct from the manufacturer can help save you money without sacrificing quality and accuracy. Manufacturers offer a variety of hearing care products to serve patients of any age. Peruse offerings from these clinical audiometer and typamometer manufacturers.

I recommend: Benson Medical Instruments is an audiometer manufacturer that allows you to compare its products side by side on its website. Bernafon Innovative Hearing Solutions manufactures numerous hearing care products, from testing equipment to hearing aids.

Buy from sellers of audiometer equipment online

If you're in a pinch and need new audiometer equipment fast when existing equipment breaks or needs repair, look to online sellers of audiometer and tympanometer equipment for help. These audiometer sellers allow you to purchase new and used equipment at discount prices.

I recommend: Scientific Equipment Liquidators sells audiometry equipment for adults and infants, while KahnTact USA offers a full line of diagnostic audiometer and tympanometer equipment.

Audiological evaluations assess any types of hearing problems and, if found, the degree of hearing impairment for prompt treatment. To accurately assess hearing disorders and ear diseases, audiologists perform hearing tests using specific types of equipment to aid in diagnosing and treating these types of disorders, including audiometers and tympanometers. Audiometers are a machine utilized to test the actual hearing of a person. Tympanometers help to diagnose all types of middle-ear disorders, which indicate the possibility of Eustachian tube dysfunction. It is important to know the key terms for hearing assessment and measurement.

Tympanometer

A tympanometer helps to diagnose middle-ear disorders, which can indicate a type of dysfunction in the Eustachian tube. The device changes the air pressure in the ear and makes it move the eardrum both back and forth, and can help diagnose tumors in the middle ear, perforated eardrums, impacted wax and other middle-ear disorders.

I recommend: Medline Plus has detailed information on the process of tympanometry and indications for usage, as well as possible disorders of the middle ear and other testing that can aid in diagnosis.

Audiometer

Audiometers test how well the ear is functioning and how well the nerve relays information to the brain.

I recommend: For an overview of audiometers, Medical Discoveries has an easy-to-read summary on the subject.

Bone-conduction test

Bone-conduction tests assess how soft a sound a person can hear over several pitches and frequency and can determine the extent to which there is a neurosensory hearing loss.

I recommend: The Medical College of Wisconsin Hearing and Balance Center has details regarding the process and procedure for bone-conduction tests.

Pure-tone audiometry

Pure-tone audiometry testing assesses the amount of noise sensitivity transmitted through the outer, middle, and inner ear and then brain. This is done using headphones, which are placed over the ears to reduce ambient noise.

I recommend: American Speech-Language-Hearing Association has complete information concerning this type of testing, as well as other important information regarding hearing examinations.

Auditory brainstem response

Auditory brainstem-response testing is done to screen for deafness and hearing loss in newborn children. It is used as a method to help assess ear function, cranial nerve function and other types of specified brain functions within the lower aspect of the auditory system.

I recommend: Web MD has further information on this subject.

Audiogram

An audiogram is done to show hearing capacity via a graphic representation and indicates the minimum intensity of sound that a person's ear can detect. It also evaluates the loudness of sound needed for hearing the tones in the musical scale. This chart or graph is the result of the hearing test conducted with audiographic equipment.

I recommend: The BC Children's Hospital has additional information on audiograms.
