Our team is brought together by the common goal of providing the best possible care and treatment to our patients with hearing problems. BHII brings together a multidisciplinary team of ENT surgeons, Audiologist, Speech & language pathologist and other support staff who provide innovative and individually tailored treatment plan for all types of hearing, speech, voice and language disorders. We have the best AVT room, Vertigo clinic and state-of-the-art audiology equipments with highly reliable results. Our expertise is provided from two serviced locations in Koramangala, Bangalore. The team will ensure the best standard of care and infrastructure in our centre and all our affiliated hospitals
Assessments
Pure Tone Audiometry
Pure Tone Audiometry (PTA) relies on single frequency tones, or "pure tones," which are transmitted via air and bone conduction pathways. The subject must respond by raising their hand or pressing the response button every time they hear the test tone. As the intensity of the tone is varied, the audiologist attempts to determine at what level the patient responds at least 50% of the time. These levels are known as the audiometric thresholds for that frequency. An audiogram is plotted based on the thresholds for all the frequencies, which gives information about the type and severity of hearing loss.
Acoustic Immittance
Acoustic immittance testing is to evaluate the function of the tympanic membrane and the muscle reflexes surrounding it.This testing helps in localizing the site of lesion. Acoustic immittance testing may include tympanometry and/or acoustic reflex testing. Tympanometry is a measurement of middle ear function. The response (mobility) of the tympanic membrane to this sound is measured at different air pressure levels
The Acoustic Reflex Threshold (ART) is the sound pressure level that elicits stapedial muscle contraction.. Ipsilateral and contralateral evaluation of acoustic reflexes is performed to assess the integrity of the acoustic reflex pathway.
Otoacoustic Emission (OAE)
An OAE is a sound generated from the cochlea in response to an auditory stimulation. The measurement of OAEs is used to assess cochlear function and is helpful in the process of differential diagnosis. Absent OAEs may be a sign of hearing loss or a blockage in the outer or middle ear.

Brainstem Evoked Response Audiometry (BERA)
ABR is an early evoked potentials and an objective tool to assess estimation of hearing sensitivity, neural integrity and synchrony. The ABR is a synchronous electrical activity in response to auditory stimuli arising from cochlea, the 8thcranial nerve, and the brainstem. The procedure involves placing electrodes on the mastoid and forehead and then administering sound stimuli (e.g., clicks) through insert earphones to detect the electrical stimulation activity from the auditory nerve to the inferior colliculus. ABR testing can also be used for a differential diagnosis of cochlear hearing loss versus retrocochlear hearing loss (e.g., caused by tumors of the vestibulocochlear nerve/CN VIII).
Vestibular Evoked Myogenic Potentials (VEMP)
VEMP is a neurophysiological assessment technique which is used to assess the function of the otolith organs and the CN VIII. There are two different types of VEMP testing, cVEMP and oVEMP. VEMPs are recorded by sending sound to the inner ear. The cVEMP response measures the integrity of the saccule and inferior vestibular nerve, while the ocular VEMP (oVEMP) measures the utricle and superior vestibular nerve. it is a short latency electromyograms (EMG) that are evoked by high-level acoustic stimuli and are recorded from surface electrodes over the tonically contracted sternocleidomastoid (SCM) muscle.
Videonystagmography (VNG)
VNG is used to measure and record a patient’s eye movements, including nystagmus, during a variety of tasks and conditions. VNG is an standard in balance assessment, uses infrared video technology to record eye movement.it is mainly used in assessing and recording of nystagmus (e.g., gaze-evoked, spontaneous) and allows for measurement of nystagmus intensity and direction.VNG helps in diagnosis of vestibular and balance related disorders.
