Audigram

An audiogram is a graphical representation of the results of a hearing test using an audiometer. It is a curve that represents the volume level of sound heard by the patient as a function of frequency.

An audiometer is a device that is used to measure hearing function. It allows you to determine how well a person hears sounds of different frequencies.

To perform audiometry, the patient must sit in a quiet room and listen to sounds of different frequencies through headphones. The results are then recorded on a graph.

On the audiogram you can see which frequencies the patient hears best and which ones worse. This helps the doctor determine whether and what kind of hearing loss the patient has.

In addition, audiometry can be used to diagnose various diseases, such as sensorineural hearing loss, Meniere's disease and others.

Overall, the audiogram is an important tool in the diagnosis and treatment of hearing disorders. It allows you to obtain detailed information about the state of the patient’s auditory function and select the most effective treatment method.

An audiogram is a graphical representation of data obtained during audiometric testing. It shows how the patient perceives different frequencies of sound and allows you to identify hearing impairments.

During audiometry, the patient wears headphones and listens to sounds of varying volumes and frequencies. At the same time, he notes which sounds he understands and which he does not. The results are recorded in the form of a graph, where the sound frequencies (from 250 Hz to 8 kHz) are plotted on the abscissa axis, and the volume level (in decibels) is plotted on the ordinate axis.

The audiogram shows how the patient hears sounds of different frequencies at different volume levels. For example, if the graph shows that the patient hears a sound at a level of 10 dB at a frequency of 500 Hz, then this means that he has hearing at this frequency and at this volume level. If the sound at a given frequency is not audible, then there will be a space on the audiogram.

An audiogram is an important tool for diagnosing hearing impairment and determining its severity. It allows you to determine which sound frequencies the patient hears well and which ones poorly, and at what volume level. This helps the doctor choose the most effective therapy and prevent the development of complications.

In addition, audiometry can be used to monitor the effectiveness of treatment and assess the dynamics of the disease. For example, repeat audiometric testing may be performed after therapy to assess how much the patient's condition has improved.

Among the huge number of methods for diagnosing hearing disorders, the audiogram receives special attention and demand. It allows you to get an idea of ​​the state of a person’s hearing, determine its deficiencies and thereby develop preventive and treatment measures for the speedy restoration to the full extent of this important function.

An audiogram is a technique for graphically displaying a person’s hearing sensitivity by frequency. Tone sensitivity recording is based on bioacoustic emissions, that is, sound signals that are easily detected by a conventional outdoor acoustic sensor and can be converted into graphic data. Thus, when conducting auditory perception studies using an audiometer, you can clearly see the quality (defects) of the frequency test being carried out at the moment.

The hearing threshold is determined using an individual audiometer, which has the ability to transform the perception of sounds, their recognition and registration on a specialized digital analyzer. The graph presented to us by the device is the response of the audiogram.

The operating principle of an audiometer is based on the physiology of hearing, which demonstrates how sound vibrations relate to the frequency of the nerve impulse wave in the cochlea of ​​the human ear. Thanks to this study, it is possible to determine a change in human perception from a couple to several hundred hertz (depending on the size of the hearing defects).

Audimetry must be carried out entirely independently due to strict rules for isolating the workplace and installing the necessary medical devices. Before you begin recording tone curves, you should carefully read the instructions for the audiometer. This instrument is used to measure changes in the patient's subjective experience of loudness and timbre (pitch). While operating this equipment, the employee must be aware of the measurements and results obtained. And especially carefully - when recording mid-frequency tone curves with operating levels (500, 1024, 2048, 4096 Hz).
