What is an acoustic reflex?

Acoustic reflex is a type of muscle contraction that takes place in the ear. More specifically, this uncontrollable muscle movement occurs in the middle ear when the area is stimulated by high intensity sound. It can also be known as reflex attenuation, auditory reflex or stapedius reflex. When the sound with a high back reaches the middle ear, two muscles-stapedius and Timpani-with tensor are found in the bony part of the ear called Osicless Contract. When these muscles move, each withdraws other muscles from thin tissue of the eardrum. Stappedius pulls the middle ear staples, while the tensor tympanic pulls a hammer in the shape of a middle ear called Malleus. Cochlea is vital because it converts vibrations into electrical impulses, which are then sent to the brain and thus create hearing. This part of the ear is filled with liquid and contains small hair that moves in response to vibrations, and these hair can be easily damaged by violent pressure. The acoustic reflex protects against this type of damage.

The type of acoustic reflex may also occur after an individual interview. The act of speaking can increase the sound pressure in Kochlea so that reflex may be required. Like its peers, this reaction reduces the levels of sound measurement known as decibels. Acoustic reflexes are lowered around 70 to 90 decibels on the spectrum of measuring the intensity intensity as outlines of the same hemility.

Although the acoustic reflex usually works in response to high intensity sounds, it can sometimes be caused by less intense sounds. However, if this answer occurs frequently, this may signal the ear problem as hyperacusis, which is extreme sensitivity to certain sounds. Likewise, the failure of any sounds to call an acoustic reflex can also indicate a problem. Another condition that relates to acoustic reflex is damage to the face nerves. Since the ear stappedius muscles and facial nerve are joined, dysfunctionIt often affects the other area in one area.

Due to its role in the detection of certain diseases, many doctors will be tested by acoustic reflex. Experts specializing in audiometry or testing of hearing capabilities are particularly interested in hearing reflexes. A device called a tympanometer can measure the effects of different sound levels on the inner ear. Abnormalities may indicate hearing loss or even a nervous system deficit. However, these tests can bring inconsistent results.
