How the test works
We use a modified ascending–descending threshold method, presenting pure tones at calibrated frequencies — 250, 500, 1000, 2000, 3000, 4000, 6000, 8000 Hz — to each ear independently. Tones are randomised in timing to discourage anticipation. Your threshold at each frequency is the lowest level you reliably detect.
Pure-tone average (PTA) is the mean of thresholds at 500, 1000, and 2000 Hz — the speech-critical band. PTA underpins the loss-severity classifications used worldwide.
Reading an audiogram
Frequency runs across the X-axis on a log scale (low pitches left, high pitches right). Hearing level runs down the Y-axis from 0 dB HL at the top to 110+ at the bottom — so a steeper drop on the chart means worse hearing. Right-ear thresholds are marked with red circles; left-ear thresholds with blue crosses.
A "ski-slope" pattern — normal hearing in the lows, sharply diminished in the highs — is the classic signature of noise-induced loss, often beginning at 4 kHz.
Limitations of at-home testing
This tool produces a screening estimate, not a diagnosis. Without a calibrated audiometer, sound-treated booth, and bone-conduction transducer, we cannot distinguish conductive loss (middle-ear) from sensorineural loss (cochlear/neural), cannot measure tympanic compliance, and cannot rule out retrocochlear pathology. Treat all results as a starting point for a professional evaluation, not a substitute for one.
