Pure Tone Audiometry is the key hearing test used to identify hearing threshold levels of an individual, in order to determine the degree, type, and place of hearing loss. The threshold levels is the lowest amplitude (at a fixed pitch) that is responded to three times. It is a subjective and objective measurement of an individual’s threshold, as it relies on the patient’s response to pure tone provided. However, it is necessary for the materials do be functioning, as well. If a material (i.e. headphones) is not working, it becomes an objective problem and unrelated to the patient’s hearing abilities (Huizing 2009). The goals of pure tone audiometry include: to find out if hearing loss is present, to find out the type of hearing loss, to find out the degree and pattern of hearing loss, to help in hearing aid selection, to help in identifying functional hearing loss, and to help find the site of For the purpose of this class, each student had a turn to perform the pure tone audiometry and to be the patient. Next, a pure tone staring from 40 dB HL at 1 K Hz was given. The bracketing procedure (decrease by 10 dB if patient can hear the stimuli then increase by 5 dB when patient stops hearing the stimuli) was followed. The threshold is found when the lowest positive response to a stimuli is found 50% of the time (however, during class, threshold was found when lowest stimuli was found 3 times). Furthermore, everything is repeated for different frequencies, including, 2000 Hz, 4000 Hz, 8000 K Hz, 250 K Hz, and 500 K Hz. Next, the pure tone average (PTA) is found among the thresholds of 500 Hz, 1000 Hz, and 2000 Hz. The next step required is a repetition of all of the previous steps, while using the bone vibrator instead of the headphones. If required, masking of bone connection and air conduction will follow. Finally, a diagnosis of severity, pattern, and type of hearing loss will be
This is a written report where my partner on the topic and I presented a ten minute oral summary of our chosen research topic on Technicolor. We chose Technicolor as we felt it had most to say to us, threw the progression of the technology the problems threw out the years of perfecting the technology, to the ultimate glory of the Technicolor experience.
Technology nowadays is getting more and more dangerous, especially to our ears. Every day we are subjected to videos, text sounds, alert sounds, alarms, and anything else that may be of use in life. These sounds seem to be happening more often which is damaging our ears. There is a solution to this damage though, and that is cochlear implants. These implants will bypass the damaged part of your ear to give you a sense of sound that can be made very useful to the patient. This paper will look into how the ear works, how hearing loss happens, why these cochlear implants are a good solution, how these implants work, cost and ethics related to these implants, and what the future holds for them.
... Association, if a the sound of a plane taking off is 1,000,000,000,000 times the threshold sound, and if the sound of a hand drill is 10,000,000,000 times the threshold sound, during which sound would you wear hearing protection?

There has to be an understanding of how the ear works, what hearing loss is before looking at the treatments for hearing loss. Hence the essay will go through how the ear works and what causes hearing loss first. Then it will explain the diagnosis process before focusing on the treatments. the essay will be exploring the past, current and the possible future treatments. The essay will also touch upon other ways in which hearing impaired people cope with hearing loss.
Forensic audiology involves applying the knowledge on hearing science and audiology to legal issues. It is not considered as a sub-specialty in audiology, rather, it’s an application of expertise in acoustic, psychoacoustic and noise to work within the legal system. It covers a board spectrum of cases such as occupation or environmental noise, audibility, speech understanding, the effects of noise, pediatrics, central auditory processing and cochlear implants. Forensic audiology is often associated with working with an attorney, especially for cases that involve workers compensation, administrative law and constitutional law.
Deaf people make unique population in the world today but unfortunately, deaf population may extinct due to widespread use of bionic ears, which is cochlear implant. Cochlear implant is a surgically implanted electronic device that provides a sense of sound to a person who is profoundly deaf or hard of hearing. The cochlear implant controversy therefore involve questions about allowing cochlear implant for newborn to ten years old or does the cochlear implant pose a serious threat to deaf community or why wouldn’t a deaf person want to become hearing and forth on. It is harmful both to individual health and the deaf community.

Hearing loss is a major global public health issue. Hearnet (2017) defines hearing loss as “a disability that occurs when one or more parts of the ear and/or the parts of the brain that make up the hearing pathway do not function normally” (para. 1). There are many different types of hearing loss, which can have multiple causes, giving each individual experiencing the issue a unique hearing loss case. These types include Auditory Processing Disorders, when the brain has problems processing sound information; Conductive Hearing Loss, a problem with the outer or middle ear which prevents sound making its way to the inner ear; and Sensorineural Hearing Loss, when the Cochlea or auditory nerve is damaged and cannot
Three coordinate systems are utilized when attempting to locate a specific sound. The azimuth coordinate determines if a sound is located to the left or the right of a listener. The elevation coordinate differentiates between sounds that are up or down relative to the listener. Finally, the distance coordinate determines how far away a sound is from the receiver (Goldstine, 2002). Different aspects of the coordinate systems are also essential to sound localization. For example, when identifying the azimuth in a sound, three acoustic cues are used: spectral cues, interaural time differences (ITD), and interaural level differences (ILD) (Lorenzi, Gatehouse, & Lever, 1999). When dealing with sound localizaton, spectral cues are teh distribution of frequencies reaching teh ear. Brungart and Durlach (1999) (as seen in Shinn-Cunning, Santarelli, & Kopco, 1999) believed that as the ...

Living in a world with no sound whatsoever is a reality to millions of people worldwide, regardless of age, race, gender, and socioeconomic status. Approximately 5% or 360 million people of the world’s population have deafness or hearing loss, according to the World Health Organization. Deafness can be either acquired or congenital depending on several factors, including genetics and health of the individual. Congenital deafness is the loss of hearing present at birth. Being born deaf has many consequences, both positive and negative. According to the American Speech-Language Hearing Association, over 50% of congenital deafness is due to hereditary and genetic issues. However, non-genetic factors can cause deafness in an individual at birth as well. Disease and illness while in utero of either the mother or child can cause the child to become deaf...
As the literature of sound symbolism grew, the potential of employing sound symbolic tactics in brand naming has been gaining attention from marketers. A brand name comprises of one or more phonemes and previous literature has shown that through sound symbolism, it is possible for individuals to infer meaning from unfamiliar brand names. In other words, individuals are able to form expectations of the properties of products through exposure to their brand names.
