All Your Hearing Care Needs at One Place
Pure Tone Audiometry (PTA)
Pure Tone Audiometry (PTA) is a hearing test performed on the ears by measuring the smallest amplitude of sound waves in the absolute-tone test. This test can be performed with or without a microphone. It is the most accurate way to determine when the correct amount of hearing aids will be suitable for an individual. IHC performs PTA tests at affordable rates in Pakistan.
Tympanometry
Tympanometry is a hearing test showing how well your middle ear works. It does this by measuring how your eardrum moves. Your ear consists of three parts: the outer ear, the middle ear, and the inner ear. Sound enters through your outer ear as energy or vibrations. The energy strikes your eardrum (located in your middle ear) and travels to your inner ear and brain.
BERA
The brainstem evoked response audiometry (BERA) is an objective neurophysiological method for the evaluation of the hearing threshold and diagnosing retro-cochlear lesions. The aim of the study was to investigate the hearing level in children with suspected hearing loss or pathological speech development.
ASSR
The auditory steady-state response (ASSR) is an electrophysiologic response to rapid auditory stimuli. The goal of ASSR is to create an estimated audiogram from questions regarding hearing, and hearing loss. ASSR allows the hearing care professional to create statistically valid audiograms for those unable or unwilling to participate in traditional behavioral tests
ABR
The ABR test assesses how a child’s hearing nerve reacts to various noises. Electrodes are placed on a child’s head and in front of his or her ears and connected to a computer. Tests use a sophisticated computer to assess the child’s ability to hear.
Audiometry (AC,BC)
An audiometry evaluation is a non-invasive, painless hearing test that assesses a person’s ability to differentiate between different sounds, pitches, and frequencies. Patients with a tumor in or around the ear may receive audiometry testing to see if they have developed hearing loss or to monitor their hearing before and after surgery.
