How to Read an Audiogram: A Simple Guide for Beginners

If you've ever taken a hearing test—whether on the Yeasound website or directly in the Yeasound app—you may have received a graph full of lines, symbols, and numbers called an audiogram.

At first glance, an audiogram can look confusing. But once you understand a few basics, it becomes much easier to read and understand what your results really mean.

If you haven't tried it yet, you can take a Yeasound hearing test online or in the iYeasound app first, then come back to this guide to learn how to read your results step by step.

What Is an Audiogram?

An audiogram is a chart that shows:

  • How loud a sound needs to be for you to hear it
  • At different pitches (frequencies)
  • For each ear separately

In short, it is a visual picture of your hearing ability.

The X-Axis: Pitch (Frequency)

The horizontal axis (X-axis) shows frequency, measured in Hertz (Hz).

  • Low pitches are on the left
  • High pitches are on the right

Typical frequencies on an audiogram include:

  • 250 Hz – very low-pitched sounds (like thunder)
  • 500–1000 Hz – many vowel sounds (like a,o)
  • 2000–4000 Hz – important speech clarity sounds (consonants like k, f)
  • 6000–8000 Hz – very high-pitched sounds (birds chirping)
👉 Speech understanding mainly depends on the middle to high frequencies, especially 1000–4000 Hz.

The Y-Axis: Loudness (Hearing Level)

The vertical axis (Y-axis) shows loudness, measured in decibels hearing level (dB HL).

This part is often confusing because:

  • 0 dB does NOT mean "no sound", it means normal hearing level

On an audiogram:

  • Top = softer sounds
  • Bottom = louder sounds

Your hearing threshold on the chart shows the minimum loudness (in dB HL) required for you to hear a sound.
If your threshold appears lower on the chart, it means sounds must be louder before you can hear them, indicating poorer hearing sensitivity.

Left Ear vs. Right Ear: Understanding the Symbols

Audiograms use symbols to clearly separate the two ears.

Air Conduction (AC)

These test how you hear sounds through headphones.

Right ear: 🔴 O (red circle)
Left ear: 🔵 X (blue X)

Air conduction reflects the entire hearing pathway:
ear canal → eardrum → middle ear → inner ear → nerve

Degrees of Hearing Loss

Hearing loss is classified by how many decibels are needed for you to hear sounds.

Degree Hearing Level (dB HL) What It Means
Normal 0–25 dB Can hear soft speech
Mild 26–40 dB Trouble hearing soft or distant speech
Moderate 41–55 dB Difficulty with normal conversation
Moderately Severe 56–70 dB Speech sounds muffled
Severe 71–90 dB Speech very hard to hear
Profound 91+ dB Only very loud sounds detectable

Why Audiograms Matter

An audiogram helps you:

  • Determine degree of hearing loss
  • Decide whether hearing aids are needed
  • Program hearing aids accurately
  • Track hearing changes over time
But remember:
👉 An audiogram shows hearing sensitivity, not listening ability in real life.
Real-world hearing also depends on noise, distance, and brain processing.
Key Takeaway

Reading an audiogram is easier than it looks. Once you understand the axes, symbols, and degrees of hearing loss, you'll be able to interpret your hearing test results with confidence. If you have any questions about your audiogram, Yeasound's hearing experts are always here to help.
