LOW END / FREE BROWSER TOOL
Listen to individual low-frequency tones or a 12-second sweep from 20 to 80 Hz. This is a listening comparison for your setup, not a measurement of speaker response or room acoustics.
Volume warning: Low tones at high volume can damage speakers and hearing. Start low. Stop at distortion, rattling, or discomfort. Never turn up an inaudible 20 Hz tone.
Ready. Start with 80 Hz at a low device volume.
A drop in perceived loudness can reflect speaker limits, room cancellation, output processing, or your listening position. A rattle may come from a nearby object rather than the speaker itself. Move carefully and compare without changing the volume. This page does not use a calibrated measurement microphone.
Small speakers may strongly filter very low frequencies. Trying to compensate with high gain can stress a driver or amplifier before you hear a clear tone. Keep tests brief and stop when sound is uncomfortable or distorted. Never use this tool to challenge a speaker’s maximum excursion.
Begin with 80 Hz at a low device volume, then try 60 and 50 Hz. The lower presets can be hard to hear on small speakers. Keep the same low volume rather than compensating for a quiet tone.
Very low-frequency signals at excessive levels can stress speakers and amplifiers. The risk depends on the equipment and settings. Use low levels, short tests, and stop at any distortion or rattling.
Many small speakers cannot reproduce deep bass at an audible level, and some devices filter it. Room acoustics and hearing also affect the result. Silence alone does not show that your speakers are defective.
No. It plays reference tones for subjective comparison. Accurate frequency response measurements require an appropriate measurement microphone, calibration, and measurement software.
