WHAT IS CONSIDERED AS A ‘NORMAL’ HEARING RANGE?

 

When we talk about hearing abilities, "normal hearing" means hearing and detecting all types of sounds. The best audiologists in Shyambazar provide their valuable opinion to facilitate users with a better understanding of normal hearing, methods used to measure sound and the different degrees of hearing loss. Differentiating normal hearing from hearing loss involves assessing how loud sounds need to be and what frequencies one can hear.

Here's what you must know about Normal Hearing Range:

How are sounds assessed?
Sounds are assessed in frequency (pitch) and intensity (loudness).

1. Frequency Measurement (Hertz): Hertz (Hz) measures the frequency of sound waves. Higher-frequency sounds, like those from a flute or cricket, range from 20 Hz to 20,000 Hz, while lower-frequency sounds, such as those from a bass guitar or cow and also fall within this range.
2. Intensity Measurement (Decibels): Decibels (dB) gauge the loudness of sound. Sounds above 85 dB cause permanent damage to the inner ear's hair cells.

Here's a list of average decibel ratings from the audiologists who provide the best hearing loss treatment in Shyambazar:

• Breathing: 10 dB
• Normal conversation: 60-70 dB
• Movie theater: 74-104 dB
• Motorcycles: 80-110 dB
• Sporting events: 94-110 dB
• Sirens: 110-129 dB
• Fireworks: 140-160 dB

Degrees of Hearing Loss

Hearing loss is categorized into different degrees based on the volume of sounds individuals are unable to hear:

• Mild: Unable to listen to sounds below 26-40 dB
• Moderate: Unable to listen to sounds below 41-55 dB
• Moderately Severe: Unable to listen to sounds below 56-70 dB
• Severe: Unable to listen to sounds below 71-90 dB
• Profound: Unable to listen to sounds below 91 dB

Importance of Hearing Loss Testing

To retain your normal hearing and maintain healthy auditory functionality, it's essential to have an idea about the hearing loss testing methods available:

• Pure tone testing
• Bone conduction testing
• Speech testing.
• Acoustic reflex testing
• Auditory brainstem response

Whether for prevention or treatment, the bestaudiologists in Shyambazar suggest seeking a proper understanding of your auditory health to implement appropriate treatment plans and management strategies to aid faster and more accurate results.
