Audiometer

AUDIOMETER

Audiometer is diagnostic equipment used to perform audiometry test for measuring individual’s hearing threshold (a condition that is, the weakest level of a stimulus signal that the

Patient is able to hear at least 50% of the time) in clinics, physician offices, outreach centers.

Audiometers originated in the late 19th century, evolving from rudimentary devices to electronic models in the mid-20th century. With digital technology, they've become more precise, allowing standardized testing methods for assessing hearing function.

WHAT IS THE AUDIOMETRIC/AUDIOMETRY?

An audiometric test measures a patient's ability to hear sounds within a specific frequency range to check the hearing threshold and to identify and measure the level of hearing loss in a patient.

To perform this test an audiologist or other qualified professional uses an audiometer device. Depending on the test results, a referral for medical care or the fitting of hearing aids may be required..

HOW DOES AUDIOMETER WORK TO IDENTIFY HEARING LOSS?

As we discussed above, audiometers are used to assess hearing abilities and diagnose hearing loss.

It performs audiometry test across a range of frequencies (Vary device to device) and delivers them to the patient through headphones or bone conduction transducers.

After that, the patient responses whenever they hear a sound, allowing the audiologist to determine the hearing threshold for each frequency.

After determining hearing threshold the report is generated called audiogram, this report helps identify patterns of hearing loss in a patient.

Healthcare professionals interpret the audiogram to diagnose hearing loss condition like a sensorineural hearing loss, conductive hearing loss and mixed hearing loss.

Types of Audiometers

There are Four types of audiometers conventional, digital, hybrid and Portable :

Conventional Audiometers

Conventional audiometers are the oldest type of audiometer, and they are still in use today. They use a series of buttons or dials to control the frequency and intensity of sound. The audiologist uses headphones to deliver sound to the patient, and the patient responds to the sound by pushing a button or raising a hand.

Digital Audiometers

Digital audiometers are the most advanced type of audiometer. They use microprocessors and software to generate and control sound. Digital audiometers offer many advantages over conventional audiometers, including better accuracy, greater precision, and more comprehensive testing capabilities.

Hybrid Audiometers

Hybrid audiometers combine the best of both worlds. They use digital technology to generate and control sound, but they still use the traditional headphones and response buttons of conventional audiometers. Hybrid audiometers offer greater flexibility and control over testing parameters than conventional audiometers, while still maintaining a familiar interface for patients.

Portable Audiometers

Portable audiometers are designed for use in the field or in remote locations. They are typically lightweight and compact, and they can run on batteries or DC power. Portable audiometers are ideal for hearing screenings in schools, nursing homes, and other community settings. They are also useful for audiologists who travel to different locations to provide services.

FEATURES OF AUDIOMETER

High-Frequency Testing

Some audiometers offer extended high-frequency testing capabilities, allowing assessment of hearing sensitivity beyond the standard frequency range.

Real-Time Monitoring

Capability to monitor test progress in real-time, allowing adjustments during testing as needed.
