screening tests

Otoacoustic emissions

brainstem evoked auditory response

confirmatory tests

auditory braintem response

auditory steady state response

A computerized hearing test used to measure the

brain waves the ear produces when it hears sound

Brainstem Evoked Auditory Response (BERA

Test the neural integrity of the auditory nerve

Brainstem Evoked Auditory Response (BERA

detect small lesions and brain tumor

Brainstem Evoked Auditory Response (BERA

use to test for conductive hearing loss

Auditory Brainstem Response (ABR)

Test for newborns, use to grade the hearing loss and

adjust hearing aids

•Auditory Steady State Response (ASSR)

can hear spoken voice at a distance of 18 feet

no loss of hearing exceeing 20 dB

Normal

cannot hear beyond a distance of 12 feet | a loss between 20-40 dB

Mild Hearing Loss

cannot hear beyond 3 feet | a loss of up to 60 dB

Moderate Hearing Loss

cannot hear a conversational voice but is able to understand spoken voice if amplified (person uses a hearing aid) a loss of 60-80 dB

Severe Hearing Loss

unable to hear spoken voice/loud sounds but maybe | improved by amplification (cochlear implant);a loss of >80 dB

Profound Hearing Loss

Types of hearing los

Conductive sensorineural Mixed

blockage to the external ear to the middle ear, normal bone conduction but abnormal air conduction, both has a distance of more than 10 dB from each other

Conductive

type of hearing loss that affects inner ear, cochlear nerve and auditory pathway

Sensorineural

type of hearing lo that affects outer ear to mid ear

conductive

usually seen in congenital hearing loss, abnormal bone and air conduction with a distance of less than 10 db.

senorineural

abnormal bone and air conduction with a distance of more than 10 dB in patients with chronic otitis media in which infection extend into the inner ear

mixed

Results from an abnormality of the outer or middle ear/ usually temporary and treatable with medications or surgery

conductive

Intervention for hearing loss

hearing aid surgery speech and OT counselling

when i the right time to screen

on or after 24 hrs after birth not more than 3 mo if home delivered: 2 mo
