If you’ve ever had a hearing test, you may remember seeing a chart filled with numbers measured in dB, or decibels. But what do those numbers actually mean—and how do they relate to how well you hear? Let’s break it down. A decibel (dB) is a unit used to measure the loudness of sound. In hearing tests, decibels indicate the softest sound you can hear at different pitches (frequencies). The lower the dB number you can hear, the better your hearing sensitivity at that pitch.
How Are dB Levels Are Used in a Hearing Test?
During a hearing test, you’ll wear headphones and respond when you hear tones at different pitches and volumes. The audiologist records the quietest level you can hear each sound—this is called your hearing threshold, measured in dB. These results are plotted on an audiogram, which helps determine whether hearing loss is present and, if so, how severe it is.
Here’s a general guide to hearing levels based on decibels:
-
-10 to 25 dB: Normal hearing
-
26 to 40 dB: Mild hearing loss
-
41 to 55 dB: Moderate hearing loss
-
56 to 70 dB: Moderately severe hearing loss
-
71 to 90 dB: Severe hearing loss
-
91+ dB: Profound hearing loss
Someone with hearing loss may still hear louder sounds clearly but struggle with softer sounds—like whispers, children’s voices, or speech in background noise. While dB levels are an important part of a hearing test, they’re just one piece of the puzzle. Your lifestyle, listening needs, and communication challenges are equally important when determining next steps. If you’re noticing difficulty hearing—or if it’s been a while since your last test—having your hearing checked can provide clarity and peace of mind.
Healthy hearing starts with understanding your results—and we’re here to help every step of the way.
