In the first chart, you have the distinction between soft sounds (from water drops and leaves), to medium and moderate noises (baby cries, a dog barking, and the sound of a piano), to very heavy noises (like music during a concert or a plane). Each of these noises are represented in terms of their pitch (measured in frequency), and in terms of loudness (measured in decibels). The second audiogram also follows this logic, but with less details, where your level of noise intolerance is measured vertically and horizontally. With both audiograms, the further down (vertically) you go into the graph, the least noise tolerant you become. As a first exercise we would like to give you a small frequency exercise, so that you can define how severe your hearing loss (whether you suffer from tinnitus or any other hearing loss condition). Before you complete this exercise, you should note that tones go from 8Hz all the way up to 22,000 Hz (where people over 25 are not able to hear above 15KHZ). Also, the commonly hearing range for humans is 20 Hz to 20KHZ. Below we have listed a series of frequencies (ranging from 0KHZ to 22KHZ). The aim of the exercise is to listen to each tone and note when your hearings cuts out. Start the exercise by turning the volume down on your headphones or speakers and then gradually turn it to a safe level (not too high). Overall, if you need to increase the volume as the frequency increases, then you have a serious hearing problem. Take a listen:
Hearing loss continues to linger in the elderly population of today’s society. Yet, the onset of hearing loss can occur at any age and at any point in
This happens in two ways: listening at too high of a volume, or listening for too long. Studies have confirmed the obvious fact that “the louder the noise and the longer you’re hearing it, the greater the risk of hearing loss” (Siegel). This study concluded that an increasing amount of teens are suffering hearing loss and “wearing earbuds to listen to music may be to blame” (Siegel). The knowledge of loud sounds hurting the ear is well known, but not as many people are aware of the problems caused by listening to music for an extended amount of time. “Constant low-level noise might cause hearing problems, a new study in rats finds” (Cheung). Even music at a low level can damage a listener’s hearing if heard for an extended period of time, but what can losing some hearing really do to a
The ear is an extraordinary human organ that many people take for granted until it doesn’t function. It is the only device that allows the human to hear sounds in their environment. The ear is made up of many parts that distinguish various sounds through different means. The ear anatomy and physiology along with how sound waves are transmitted into meaningful sounds will help one understand how hearing loss occurs.
In this experiment, the signal generator was set so that the frequency meter showed a reading of 1,803 Hz. The microphone was moved to a distance from the speaker so that the oscilloscope displayed a straight diagonal line. This position was of the microphone was recorded as the initial position, or beginning of a wavelength. The microphone was then moved farther in the same direction until the oscilloscope displays the same horizontal line. This position was recorded as final position, or the end of the wavelength. The distance between the two positions represents one wavelength for this frequency. This was repeated for frequencies of 2,402 Hz, 3,002, Hz, 3,602 Hz, and 4,201 Hz.
The documentary Deaf Jam produced by New Day Films provided an in-depth look into the beauty and dexterity of American Sign Language (ASL) while highlighting many important aspects of deaf culture. It also gave an even deeper analysis of the personal lives of those who are deaf and the societal and emotional struggles they face every day. This was done through the eyes of an Israeli immigrant named Aneta Brodski and her empowering journey to share her story through signed slam poetry.
Tinnitus ‘is a term that describes any sound a person can hear from inside their body rather than from an outside source’ (nhs, 2013). People usually hear sounds such as ringing, buzzing, humming or machine type noises. ‘Sometimes the noise pulsates at the same rate as your pulse’ (knott, 2012). The noises may vary in pitch and intensity and can come from either ear or both. The noise is more noticeable in a quiet place and people may find they are becoming more sensitive to normal everyday sounds.
"What it is telling us is the sound is located between about 7,000 kHz and 8,000 kHz. There are about 20 peaks, and they seem to be equally spaced. All these peaks correspond to a different frequency," said Kausik Sarkar, an acoustics expert and engineering professor at The George Washington University who reviewed the recording with the AP.

Program directors’ decision to only test frequencies at 1000, 2000, and 4000 Hz, while excluding 6000 Hz, will inevitably miss students with a hearing loss in higher frequencies. Assessing the efficacy of the hearing screening program led researchers to make recommendations for other universities to implement. Examples include, advocating the importance of follow-up to students to improve return rates, and having proper sound treatment to enhance screening results. Finally, adding 6000 Hz into the screening program may help to accurately identify students with early signs of high frequency hearing loss. In conclusion, the study was useful in acknowledging weaknesses such as assessing the low follow-up rates, noticing high levels of noise, and examining the impact on results when hearing screening programs choose to omit 6000 Hz. Recognizing the limitations of the hearing screening program allows for given recommendations to strengthen the efficacy of existing hearing screening
As a veteran, John was exposed to loud noises while on duty many years ago. Due to his prolonged exposure, John developed severe sensorineural hearing loss. Along with hearing loss, he also suffers from tinnitus. This interview was conducted in a quiet environment and directly facing John. John began the interview
Age is the most common factor in increasing hearing loss. About 30 percent of people between 65 and 74 experience some difficulty in hearing. That percentage and the severity of the loss increase with age.
The first time I learned about the ideas similar to sum class was when I read Richard Cohn’s Audacious Euphony, and I was fascinated by how much information about voice leading can be facilitated by just summing up the pitch class collection. I am excited to read this paper, which extends the discussion from diatonic triads and tetrachords to more set classes, and how much of the similar voice-leading properties are retained. There are, however, multiple questions that I am not sure about the spaces created in the paper, as well as those by Tymoczko and many others, in terms of its musical value. I am also not sure about the use of the pitch-class clockfaces and the current representation of pitch center of balance, and I wonder if there is
A hearing protection device (HPD) is often used as a protective measure in a workplace environment when the sound levels of that environment cannot be decreased and such levels pose a threat to the hearing of workers. An HPD is a safety device worn by individual’s to protect his or her hearing from the harmful effects of sound (Berger, 2003). A variety of occupational environments are known to produce high levels of noise, including factories and military operations. Individuals employed in these professions may be required to wear HPDs to reduce the risk of noise-induced hearing loss. However, certain situations in these work environments require the listener to also be able to hear low-level sounds for safety reasons.
Hearing loss and loud music have been linked together since the beginning of music. But, that is because the correlation is real. Spinning classes are known for pumping loud music into the studios to help mentally fuel a workout. Most Spinners will probably tell you that the music helps their workout, or at least helps them keep their minds off of the intensity of it. Even though music may be the great motivator of a Spinning class, there is a good chance that it is damaging the hearing of the participants as well.
