What is the definition of auditory acuity?
Auditory acuity designates The capacity of the human ear to perceive sounds. It is specific to each individual and evolves throughout life. It can be determined by Hereditary factors, by age or by ear training to the perception of frequencies. Auditory acuity can be Measure by an audiometric testor audiogram, which consists of listening to frequencies of variable intensity, by means of specialized audiometric equipment.
Audiometry is the Hearing test which makes it possible to assess the type and degree of hearing decline. “This test is carried out with a helmetin an soundproofed environment. This equipment makes it possible to look for the smallest auditory sensation perceived on different frequencies: serious, mediums and treble “underlines the general practitioner.
What is normal auditory acuity?
Hearing acuity Between 0 and 20 dB is considered normal. In a teenager, normal auditory acuity is close to 0 dB.
| Degree of hearing loss | Beach of hearing loss in decibel (DB) |
|---|---|
| Normal auditory acuity | Between -10 and 20 |
| Mild deafness | Between 21 and 40 |
| Moderate deafness | Between 41 and 70 |
| Severe deafness | Between 71 and 90 |
| Deafness | Greater than 91 |
What are the causes of decreased auditory acuity?
After 50 yearsthe ciliated cells of the inner ear gradually deteriorate and cause a drop in hearing. “In the majority of cases, presbycusia is gradually coming. This natural phenomenon is similar to that of presbyopia for vision. It is not uncommon that the people concerned do not realize it right away. It is often the entourage who pointed out to them this deficit“Observes Dr. Patrick Aubé.
When a drop in hearing is detected, we can thanks to the audiogram, quantify it by a percentage of loss.
- Between 0 and 20%: Light deafness.
- Between 20 and 60%: Average deafness.
- Between 60 and 80%: Severe deafness.
- Between 80 and 100%: Deep deafness.
What to do in the event of a drop in auditory acuity?
“The drop in hearing is not a disease or a fatality. Hearing apparatus is an aid that can significantly improve the life comfort of the person and that of those around him”reassures the general practitioner.
