Weber S Test

The Weber test is a hearing testing method in which, after placing a tuning fork on one of several points on the midline of the forehead, it is determined which ear transmits sound better.

The test procedure is as follows:

1. The patient sits up straight, eyes closed.

2. The doctor places a vibrating tuning fork along the midline of the patient's forehead.

3. The patient concentrates on the perception of the sound of the tuning fork and determines into which ear the sound is transmitted better and louder.

4. The procedure is repeated when installing a tuning fork on different points of the forehead.

In a healthy person with normal hearing, the sound of a tuning fork is transmitted equally well to both ears.

If the patient has unilateral conductive hearing loss, then the sound of the tuning fork will be better and louder in the affected ear.

Thus, the Weber test allows us to identify disorders of the conductive component of hearing and lateralize the affected ear.

The Weber S Test is one of the hearing testing methods that allows you to determine which ear conducts sound better. This test is based on the phenomenon of sound transfer that occurs in cases of conductive deafness.

Conductive deafness occurs when the conduction of sound in the outer or middle ear is impaired, for example, when sound is difficult to pass through the external auditory canal or when the integrity of the eardrum is damaged. In this case, the sound does not reach the inner ear, which leads to a decrease in the audibility of sounds.

During the Weber test, a tuning fork is placed on the patient's forehead and emits a specific frequency of sound. A healthy person hears this sound equally well in both ears, since the sound spreads evenly throughout the skull.

If one ear is affected by conductive deafness, the sound will be heard louder in the affected ear. This is because the damaged ear is unable to transmit sound waves correctly, and sound is perceived with greater intensity in the ear where the hearing aid is in better condition.

Thus, the Weber test is a simple and effective method for assessing hearing function and can be used both in the initial examination of patients and to monitor the effectiveness of treatment for deafness. However, to accurately diagnose and determine the type and degree of deafness, a comprehensive examination of auditory function is required.

The human ear, being a complex organism, has various functions that are provided by certain structures. For example, the auriculotemporal nerves lie on the glossopharyngeal nerve, and these, in turn, give rise to the cochlea, which is part of the hearing organ. Subsequently, the acoustic vibration reaches the cochlea, causing the sound wave to follow part of the bones of the facial skull. Despite this, bone conduction does not depend on sound distortions that affect the hearing perception of the human listener, while air conduction has a number of positive and negative aspects.
