Дастур

Барои фаҳмидани он, ки талафоти шунавоӣ чӣ гуна чен карда мешавад ва дараҷаҳои гуногуни талафоти шунавоӣ маълумот гиред.

Чӣ тавр чен кардани талафоти шунавоӣ

Камшавии шунавоӣ бо истифода аз аудиометр чен карда мешавад.

Аудиометр ҳаҷми садоро бо децибел (дБ) чен мекунад.

Hearing test (audiometry)

Tests how well a person hears sounds. This includes how well a person can hear different types of sound and how loud or quiet sounds are.

Дастур

In this module audiometry is referred to as a hearing test.

Шахсе гӯшмонак мепӯшад. Гӯшмонаки рост сурх ва гӯшмонаки чап кабуд аст. Одам дасташро боло мебарад. Корманди тиб дар паси шахсе, ки аудиометри планшет дорад, меистад.

Аудиограмма

The hearing test results are shown in an audiogram.

Аудиограмма оромтарин садоеро нишон медиҳад, ки шахс метавонад дар басомадҳои гуногуни садо мешунавад (ҳадди шунавоӣ).

  • Frequency (hertz) is shown with low frequency sounds on the left and high frequency on the right
  • Loudness (decibels) is shown with quiet sounds at the top and loud sounds at the bottom.

An audiogram graph of a person’s hearing test thresholds. Right ear (marked by red circles) and left ear (marked by blue crosses). The vertical axis shows sound level in decibels (dB) from 0 dB at the top down to the loudest level at 140 dB. Frequencies are on the horizontal axis from 125 Hz to 8000 Hz from left to right.

Results for each ear are shown differently:

  • Red or circles for right ear
  • Blue or crosses for left ear.

Натиҷаҳо метавонанд дар ду аудиограммаи алоҳида барои рост ва чап ё дар як аудиограмма бошанд.

Намудҳои гуногуни садоҳо (басомад)

Different types of sound (frequency) are measured in hertz (Hz).

  • Examples of high frequency sounds include a whistle and birds singing
  • Examples of low frequency sounds are a drum and chainsaw.

Савол

Ба расмҳои аудиограмма нигаред.

An audiogram graph showing different frequencies on the horizontal axis from the lowest at 125 Hz to highest at 8000 Hz (from left to right). The vertical axis shows sound level in decibels (dB) from 0 dB at the top to loudest at 140 dB at the bottom. Icons on the table show the level and type of sound. For example: • A bird chirping is at 5 dB and 8000 Hz • Tree leaves moving in the wind is at 15 dB and 2000 Hz • A person whispering is at 30 dB and 4000 Hz • A verbal conversation is at 60 dB at 2000 Hz • A chainsaw is at 100 dB at 250 Hz • A motorcycle is at 100dB at 4000 Hz • An airplane engine is at 120 dB at 4000 Hz • A firework exploding is at 130 dB at 125 Hz.

Кадом расм басомади баланд ва садои баландро нишон медиҳад?

Motorcycle is correct!

  • A motorcycle is a high frequency loud sound
  • Занҷир як садои баланд басомади паст аст
  • Рехтани баргҳо садои ороми басомади миёна аст
  • Сурудхонии паррандагон садои ороми басомади баланд аст.

"Банани сухан"

An audiogram graph showing a grey area in a shape of a banana between the area of 20 dB to 65 dB covering 125 Hz to 8000 Hz. Examples of the different speech sounds are positioned in different parts of the speech banana, across low, medium and high frequencies.

The banana shaped area on the audiogram shows speech sounds at conversation level.

The sounds in our speech have low, medium and high frequency sounds.

If a person has hearing loss, they may hear some speech sounds and not others. This makes it harder to understand what a person is saying.

As hearing loss increases it becomes more difficult to hear conversations in a normal speaking voice.

Дараҷаҳои талафоти шунавоӣ

An audiogram graph showing grade of hearing loss on the right (bottom to top): • Profound hearing loss, 80 dB and above • Severe hearing loss, 65-79 dB • Moderately severe hearing loss 50-64 dB • Moderate hearing loss, 35-49 dB • Mild hearing loss, 20-34 dB • Normal hearing, less than 20 dB.

Одамоне, ки шунавоӣ доранд, мисли одамони шунавоии муқаррарӣ шунида наметавонанд.

The results of a hearing test can be graded to six different levels for each ear. The grades are based on average hearing thresholds for each ear:

  1. Гӯшдории муқаррарӣ
  2. Аз даст додани шунавоӣ
  3. Камшавии шунавоии миёна
  4. Аз даст додани шунавоӣ ба дараҷаи миёна
  5. Норасоии шадиди шунавоӣ
  6. Аз даст додани шунавоӣ

Ҷонро дар хотир доред?

John retired after working in a noisy factory for 34 years.

He has a hearing test at his local health service. The health worker shows John his hearing test results and explains he has severe hearing loss in both ears.

The health worker explains that John may find it difficult to hear conversations.
