    Audio Test

    It's Free!

    Make sure your iPhone mute switch is NOT set to mute or sounds will not play.

    CAUTION!!!
    Use caution when playing low frequency or high frequency tones through an amplifier or through headphones or earphones. The tones may seem inaudible or lower in volume than they actually are. Hi-volume tones can cause hearing damage. Please use caution on high frequency tones at 10 kHz and above if external amplification is used or if headphones or earphones are used

    Audio Test is the simplest way to test your iPhone capable home or car audio system.

    Audio Test can be used as a simple hearing test

    Audio Test also includes 3 Audio Illusions for entertainment purposes

    All tones and illusions accessed on a single page!

    Tones range from 12 Hz to 20,000 Hz. Including:...

    Audio Test is the simplest way to test your iPhone capable home or car audio system.

    Audio Test can be used as a simple hearing test

    Audio Test also includes 3 Audio Illusions for entertainment purposes

    All tones and illusions accessed on a single page!

    Tones range from 12 Hz to 20,000 Hz. Including:

    12, 15, 20, 30, 40, 50, 70, 100 Hz
    120, 150, 200, 300, 400, 500, 700, 1000 Hz
    1.2k, 1.5k, 2k, 3k, 4k, 5k, 7k, 10k Hz
    12k, 14k, 15k, 16k, 17k, 18k, 19k, 20k Hz

    Note that for higher tones, finer steps are used to allow you to determine an accurate high frequency hearing limit.

    Under ideal laboratory conditions, humans have a hearing range of 12Hz to 22,000 Hz.

    The iPhone built in speakers are limited to a low frequency limit is around 100 Hz to 120 Hz which can only be heard in a quiet setting and with ear close to the phone.

    A home or car audio system should be able to reproduce the lower tones depending on the system capabilities.

    Multiple tones can be played by tapping two buttons in rapid succession. In this way you can demonstrate correct operation of even the lowest tones as they will produce an audible beat note when paired with a second tone.

    The typical high frequency hearing capability vs. age is as follows.

    20 kHz and 21 kHz are typically only audible to those 18 years of age or younger

    17 kHz to 19 kHz is typically only audible to those 24 years of age or younger

    16 kHz is is typically only audible to those 30 years of age or younger

    15 kHz is is typically only audible to those 39 years of age or younger

    12 kHz to 14 kHz is is typically only audible to those 50 years of age or younger

    10 kHz is is typically only audible to those 60 years of age or younger

    All ages should be able to clearly hear 7kHz

    Dogs have a hearing range of
    40 Hz to 60,000 Hz

    So dogs can hear the high tones that you may not be able to hear. Highest tones can be used as a Dog Whistle

    Elephants have low frequency calls in the 15 Hz to 35 Hz range. Call your local elephant!

    CAUTION!!!
    Do not high frequency tones at high volume or into headphones or earphones. The tones may seem inaudible or lower in volume than they actually are. Hi-volume tones can cause hearing damage. Use caution on high frequency tones at 10 kHz and above if external amplification is used or if headphones or earphones are used.

    Audio Illusions present various audio sequences that seem to rise or fall but end up going "no where" and end up back where they started.

    Make sure your iPhone mute switch is NOT set to mute or sounds will not play.
