This study was purported to examine the definition of tone deafness, various factors for the cause based on literature review of research findings, and to examine therapeutic application of music for treatment of tone deafness. With research, it was found that there can be three different kinds of tone deafness; amusia, agnosia, and asonia. Literature review showed that tone deafness has been frequently dealt in many research in order to verify the causal factors, such as gender, age, and environments. With time, the research trend on tone deafness has shifted towards neurological approach closely examining brain activity, presenting the statement that the brain's capacity to perceive modest pitch changes may be congenitally impaired. Also physiological factors contribute to tone deafness called diplacusis, which is a phenomenon wherein a given tone is heard as different pitches by the two ears, resulting in conflicting bilateral perception of pitch. Music can be used for treatment of various factors causing tone deafness. The most efficient intervention was singing program. Pitch-matching training can be effective training using operant conditioning procedure. Successive approximation or reinforcement of correct response alone was more efficient procedure in helping uncertain singers to sing on pitch. Also progressive breathing exercises helped the training the pitch-matching where one had to coordinate hearing and voice.

KID syndrome was named after the initials of the major three symptoms of the disease; keratitis, ichthyosis, and deafness. The syndrome was first introduced by Dr. Burns in 1915 who described one of his patients with those symptoms. In 1981, Dr. Skinner and his colleagues reported 17 patients who had keratitis, ichthyosis, and deafness. They also called the disease KID syndrome for the first time. After that, there have been only 60 cases of KID syndrome reported. KID syndrome may be presented with neurosensory deafness, vascularizing keratitis and such skin disorders as ichthyosis, ichthyosiform skin eruptions, and alopecia. Also, those with KID syndrome may suffer from repetitive infections, dental affections, hypohidrosis, growth delay and hepatic and renal abnormalities. The authors report the first case of KID syndrome in Korea with some references. The patient presented with keratitis, neurosensory deafness, and such characteristic skin disorders as ichthyosis and hyperkeratosis.

A 2-month-old, intact female white Bull Terrier presented because of suspected deafness. The coat color was predominantly white and the iris color, of both eyes, was brown. The dog did not respond to the owner's voice when the sound stimuli were presented outside of the visual field; however, the dog responded to visual gestures. The other physical, neurological, otoscopic, radiographic, and blood examinations were unremarkable. To assess the apparent deafness, brainstem auditory evoked responses (BAER) were recorded and analyzed in the dog with suspected deafness as well as a normal littermate. The response in the normal littermate consisted of a series of five wave peaks (I-V) with decreased amplitude and prolonged latency as the stimulus intensity decreased. The BAER from the dog suspected of deafness appeared as a flat line and did not reveal identifiable peaks that corresponded to those found in the normal littermate. Thus, congenital, sensorineural and bilateral deafness was confirmed by the BAER.

Positional cloning of hereditary deafness genes is a direct approach to identify molecules and mechanisms underlying auditory function. Nowadays many deafness genes are newly identified by finding the locus for the causative genes. Mutations at many different loci in humans and mice are known to cause hearing impairment. Mouse mutants exhibiting deafness may be useful in identifying some of genes involved. (omitted)

These experiments were designed to evaluate the possibility of brain-stem auditory evoked responses(BAER) as a diagnostic tool for deafness in dogs. The BAER was recorded from three different groups of dogs; the normal dogs,'dog with otitis externa and dogs with unilateral destruction of cochlear. BAER of the normal dogs was consisted of distinct five peaks(I, II, III-IV, V). Furthermore, the clear shapes of waveform were observed at 85 dB. The latency of BAER was increased with reducing the intensity of sound-stimulus. The highest threshold of BAER was measured at 2 KHz with 10-30 dB. Dog with otitis externs demonstrated unclear shapes of BAER compared to the that of normal dogs. In the dogs with unilateral destruction of cochlear, the flat and indistinct waveform of BAER was recorded from the cochlear destroyed ear while that of BAER from normal side of ears did not show any differences from the normal BAER. These results indicate that the BAER can be clinically used in order to diagnose the deafness in dogs.

Directional MAC protocols have drawn great attentions recently in super high speed wireless local/personal area networks due to their higher antenna gain, better spatial reuse, longer transmission range, and lower interference. Despite of these merits, directional MAC protocols suffer from deafness problem. The deafness problem occurs if a node does not answer an RTS frame addressed to it. To overcome this problem, directional MAC protocols have aimed at avoiding the deafness problem using multiple control frames or advance notice techniques or distinguishing deafness from collision. In this paper, we analyze the performance of these schemes in deafness environments with some scenarios. Through performance analysis, we compare the performance of these schemes through evaluating actual network throughput.

The purpose of this study is to investigate the correlation between aluminum form work and noise-induced deafness by conducting special health examination on construction aluminum worker and noise measurement at the workplace. All the 11 aluminum form workers were diagnosed with noise-induced deafness after holding a special health examination. The workers have not had any previous history of noise-induced deafness which indicates that aluminum form work is related to noise-induced deafness disease. The impact noise of 120 dB(A)~125 dB(A), which exceeds the regulations of industrial safety and health act, was found during the dismantling rather than installation when noise measurement was made at the aluminum workplace. The aluminum form workers could permanently lose the hearing sense if they are exposed to this impact noise. This study is to suggest the method to prevent noise-induced deafness for aluminum form workers by firstly giving out hearing protection equipment at the construction site and secondly installing rubber mat, soundproof panel as well as changing the noise-lowering technique.

A 3-month-old, intact male French bulldog was suspected of deafness. The dog was irresponsive to environmental noises generated out of sight, but normal responses were noted for visual stimuli. No abnormalities were observed on the neurological, otoscopic, radiographic, and blood examinations. To diagnose the apparent deafness, brainstem auditory evoked potential (BAEP) was recorded in the presented dog together with a normal dog. While the BAEP from the control dog showed a normal wave consisting of 5 peaks, absence of all peaks was noted in the suspected deaf dog. Therefore the dog was definitively diagnosed as bilaterally congenital sensorineural deafness.

The sudden deafness and tinnitus caused by stress is a very common otorhinolaryngologic disease. But, we do not know the exact cause and the healing method of that. We have a case report of the patient who has the sudden deafness and tinnitus caused by stress. He has also insomnia, neck pain, general weakness and so forth. In this study the patient classified by Sasang constitutional medicine had a notable medical effects. And in the result, any symptoms are not remained. So we report the healing process and result of this patient in this study.

The sudden deafness is generaly defined as sensorineural hearing loss without definite cause. The medical treatment of this disease is purposed on hemokinetic improvement and anti-inflammatory action. There are various prognoses such as perfect recovery or loss of hearing. The symptoms are easily redeveloped by fatigue or psychological stress. We treated two patients, who diagnosed as the flare of Liver fire and the flare based on insufficiency of Kidney Yin, of sudden deafness with herbal medication, acupuncture, moxibustion and herbal acupuncture. The symptoms were improved after three or four times of treatment.
