  Human ears can hear single frequencies of vibrations, ranging from 20 Hz to 20,000 Hz, known as threshold frequencies. However, age-related hearing loss, particularly at the upper limit of this range, is a natural occurrence. Studies show that human hearing is generally most sensitive in the range of 500 Hz to 10,000 Hz. Audiology deals with the study, assessment, prevention, and treatment of disorders related to hearing and imbalance. Diagnostic audiometry makes use of different hearing tests to determine the exact location due to which hearing loss is occurring. These tests include pure tone audiometry, tympanometry, otoacoustic emissions, and special speech tests and auditory brainstorm response tests.         Pure tone audiometry      It’s one of the most widely used diagnostic audiometry tests, wherein the listener’s hearing threshold level is plotted on a chart, known as pure tone audiogram. The baseline, known as audiometric...

The prevalence of hearing issues is on the rise globally, a trend attributed to the widespread use of headphones, earphones, and similar sound devices. Additionally, certain industries, such as aviation, construction, and sectors involving radioactivity, generate significant noise, putting workers at risk of hearing impairment. Understanding the serious implications of hearing impairments, it becomes crucial to recognise the importance of ear examination instruments, also known as audiology equipment , in the field of medical sciences. Let us briefly go through some of their benefits.      1.     Evaluation of Hearing   The different instruments for ear examination aid in hearing evaluation. For example, devices for otoacoustic emissions help to analyse the integrity of the cochlea in the inner ear. Tympanometers evaluate the functionality of the middle ear. Audiometers are useful in determining the hearing thresholds.       2....

As the number of technological products continues to rise, so do the associated threats. High-tech sound devices like headphones, earphones, and various speakers have not only brought convenience but also raised concerns about health issues such as dizziness, headaches, and, notably, hearing impairments. Fortunately, advancements in medical sciences have addressed these issues caused by such devices.   When we talk of hearing impairments, we shall also talk about the sectors that are heavily responsible for causing hearing ailments. These include construction, nuclear, radioactive, and airline sectors. All of them generate sounds and noise in large volumes. These sectors often generate high volumes of sound and noise, leading to reported cases of temporary or permanent hearing loss due to industry negligence.   The Importance of Audiology and Audiometry in Medical Sciences     For all such impairments related to the ear and hearing, we have the vast area ...

Hearing loss is a condition wherein a person cannot hear sounds at or above 20 decibels (dB). It can manifest in various degrees, ranging from mild to profound, and can affect one or both ears. Hearing loss can result from a variety of factors, such as early-onset childhood hearing issues, ear infections, age-related hearing deterioration, noise-induced damage, and the use of ototoxic medications. The consequences of hearing loss can be far-reaching, affecting a person's ability to communicate and potentially leading to delayed language development in children.     Hearing loss can be attributed to several causes, including aging and exposure to loud noises. It can be categorised as conductive (affecting the outer or middle ear), sensorineural (involving the inner ear), or mixed (a combination of both types). Additionally, factors like excessive earwax can impact hearing capacity.     Symptoms of hearing loss include:    ·     ...
