It is seen that the historical development of the science of audiology dates back to the early 1900s. After the Second World War, most of the war wounded were head traumas, acoustic traumas and injuries. As a result of these injuries, important problems have emerged in the treatment and rehabilitation of many patients with hearing and language-speech problems. At the end of the war years, between 1945 and 1950, this need led to the emergence of a new professional group. First, undergraduate-level schools were established in the United States to train professionally to become professionals in this field. Audiologist and Speech Pathologist took part as an independent professional group in multidisciplinary studies composed of specialties such as Ear Nose Throat, Neurosurgery, Neurology, Psychiatry, Geriatrics, Pediatrics.

Due to the reasons we have listed below, the present and future needs of societies in the world and in our country make the development of the field of audiology inevitable.

* Tinnitus and hearing loss due to acoustic trauma are frequently seen in workers working in noisy workplaces, members of the Armed Forces and Police. Because noise control and individual protectors are not used correctly and effectively, the effort and expense spent on training qualified personnel is wasted.

* There is a dramatic increase in the incidence of hearing loss with advancing age. While the incidence of hearing loss is 15-20% between the ages of 50-65, this rate rises to 30-40% over the age of 65. Increasing the elderly population day by day causes hearing loss to be among the most important problems in this group.

* After the diagnosis of hearing loss, the treatment and rehabilitation approach to be applied should be determined. The correct selection of the hearing aid, cochlear implant, brainstem implant, middle ear implant, vibrotactile device, FM device and auxiliary devices used for rehabilitation increases the efficiency of the patient. As of now, a common service understanding on hearing aid devices cannot be implemented properly in Turkey.

* Dizziness is among the primary complaints of patients who apply to Otorhinolaryngology clinics. The early return of these patients to their daily lives is possible with rehabilitation studies that support correct diagnosis and medical treatment. In addition, the weakening of the vestibular system underlies the complaints of falling due to age. It has been determined by many studies that geriatric patients in the risk group benefit a lot from vestibular rehabilitation programs and that the risk of falling is significantly reduced.

* It is a very important requirement to have the ability to speak in order for communication to take place and continue. Hearing loss that occurs at an early age is an important factor that negatively affects not only the development of language-speech skills but also the learning process. Therefore, rehabilitative processes to be applied to individuals with hearing loss should be planned in the early period.

* Newborn hearing screening results show that 3-4 out of 1000 newborns are born with hearing loss. Considering that the annual number of births in our country is approximately 1,300.00, a significant number of babies with hearing loss join us every year.

* Various studies show that the incidence of hearing loss due to ototoxic drug use, mumps, measles, meningitis, encephalitis, head trauma, etc. show).

* Increasing the risk of acoustic trauma in the young working population is among the most important reasons that increase tinnitus and hearing loss. Hearing loss is seen in this group (between the ages of 25-40) with a rate of 5-7%.
