Audiogram
An audiogram is a crucial diagnostic tool used to evaluate hearing ability. It is a graphical representation of a person’s hearing sensitivity across different sound frequencies. Conducted by an ENT specialist or audiologist, an audiogram helps detect hearing loss, determine its severity, and guide appropriate treatment.
Why is an Audiogram Important?
- Detects hearing loss early
- Identifies types of hearing loss (conductive, sensorineural, or mixed)
- Helps in fitting hearing aids or recommending treatments
- Assesses hearing for occupational or medical purposes
How is an Audiogram Test Performed?
- Patient Preparation – The test is conducted in a soundproof room to eliminate background noise.
- Pure Tone Audiometry (PTA) – The patient wears headphones and responds to sounds of varying frequencies and intensities.
- Speech Audiometry – Evaluates the ability to recognize and understand spoken words at different volumes.
- Tympanometry (if needed) – Checks for middle ear problems like fluid buildup or eardrum issues.
- Results Analysis – The audiogram is analyzed to determine hearing thresholds and identify any abnormalities.
Understanding Audiogram Results
The audiogram graph displays:
- Frequencies (Hz) – Low to high pitch sounds on the horizontal axis
- Hearing Thresholds (dB) – Softest sounds a person can hear on the vertical axis
- Normal hearing range (0-25 dB)
- Mild to profound hearing loss levels
When Should You Get an Audiogram?
- Difficulty hearing in conversations
- Ringing in the ears (tinnitus)
- Frequent ear infections
- Exposure to loud noise at work
- Sudden or gradual hearing loss
Regular hearing checkups are essential for maintaining optimal ear health. If you or a loved one experience hearing difficulties, schedule an audiogram test today!
