Results The purpose of this research was to illustrate and compare the differences in shapes of auditory filters of two individuals. The signal to noise ratio (P/N0) represented in Table 1, is a ratio of the power in the signal (P) over the spectrum level of noise (N0) which remained at 35 decibels except in the notch. The P/N0 is given in…

in a different way to help deaf or almost deaf people. Scientists however believe, that there is little hope of this happening very soon. Another thought is to present deaf toddlers with idealized synthetic speech, because this may be useful in auditory learning in the future. Through the past, science has been applied in many different ways, to help solve medical problems. Science is not only used to make important discoveries of different medicines, but also to make discoveries used for…

obtaining a correct diagnosis. Next, the otoscopic examination is performed using an otoscope. As was mentioned earlier, in order to exclude possible structural abnormalities that may affect test results, otoscopy should be included in any paediatric auditory assessment (Northern & Downs, 2014). After the clinician is satisfied with the findings, tympanometry is performed. Tympanometry is a part of a physiological objective hearing test called Acoustic Immittance Audiometry that evaluates a…

All neonates passed an automated auditory brainstem response (AABR) test and a transient evoked otoacoustic emission test (TEOAE), which showed that the neonates had no hearing loss. After the newborns passed the AABR test, they were tested using TEOAEs and HFT in a non-sound-treated room…

This paper explores the different diseases in which hearing loss is a side effect. The different causes of deafness are broad and are usually categorized between two types of deafness. There are two main types of deafness which are conductive deafness and nerve deafness. There is deafness in which you are born in (can be born in through disease), congenital deafness; and deafness which occurs later in life, adventitious deafness, usually caused by loud noises. The paper explores the Sensorial…

Otitis media is an inflammation of the middle ear without reference to etiology or pathogens. Next to the common cold, otitis media is the second most common reason that patients are seen at pediatric offices and one of the most frequent reasons for prescribing antibiotics to children (Roland, 2010). The most common bacteria responsible for ear infections are Streptococcus pneumoniae. Otitis media occurs when the Eustachian tubes are swollen or blocked and fluid is trapped in the middle ear.…

An indication that Lucas has an ear infection is that he’s not sleeping well, he hardly eats, and constantly pulling his ear. In children it might be harder to conclude what these symptoms can be exactly since they don’t really speak clearly to actually express what’s bothering them. Chronic otitis media is an inflammation or infection that lies behind the eardrum, it appears and disappears that’s why it’s considered chronic. Some symptoms of otitis media are: sleeplessness, ear pain which…

sensation because it helps the muscle to strech more since you are stimulating those areas more. What is the purpose of a cochlear implant? Is a damage hair cells in child’s, cochlea help establish some degree of hearing by stimulating the auditory nerve directly.…

Sensorineural hearing loss can result from acoustic trauma (or exposure to excessively loud noise), which may respond to medical therapy with corticosteroids to reduce cochlea hair cell swelling and inflammation to improve healing of these injured inner ear structures. Sensorineural hearing loss can occur from head trauma or abrupt changes in air pressure such as in airplane descent, which can cause inner ear fluid compartment rupture or leakage, which can be toxic to the inner ear. There has…

individuals. They compared ARs of 18 subjects under 30yearsold compared to those above 50yearsold (elderly) at a range of frequencies. They found the AR magnitude was significantly lower in the elderly, consistent with age-related changes in the auditory system and stapedius muscle. The participant tested was a 36yearold male, and therefore could have slower reflexes compared to someone under 30yearsold. The aim of this study was to test ARs and compare results with the participant’s pure-tone…
