About Warble Tones:
Warble tones are frequency-modulated pure tones used in sound field audiometry. The frequency varies around a center frequency to minimize standing wave effects in the test environment. Typical warble rates are 4–6 Hz with modulation depths of 10–20%.
A personal note:
I made this little tool to help my 3-year-old get comfortable with warble tones ahead of an audiometry test. Letting them press the button and hear the familiar sound at home took the mystery (and a lot of the nerves) out of the clinic visit. Hoping it helps another family too.
