About the Bass Test

What people use it for

- Checking a subwoofer reaches the depth it claims.
- Finding buzzes and rattles in a speaker cabinet or a car door panel.
Details
| Deepest audible bass | about 20 Hz |
|---|---|
| Typical laptop speaker | nothing useful below 150 Hz |
| Good bookshelf speaker | down to about 50 Hz |
| Subwoofer | 20 to 40 Hz |
Start with the volume low and raise it slowly. Sustained pure tones are far more damaging to hearing than music at the same apparent loudness, and asking a small speaker to reproduce very low or very high frequencies at volume can damage the driver. Very low frequencies at volume are the fastest way to destroy a small speaker, because the cone travels much further than it does for music.
Frequently asked questions
I hear nothing below 60 Hz.
That is completely normal on laptop, phone, tablet and monitor speakers — they are physically too small to move enough air. What you may feel instead is the case buzzing. Judge bass extension on headphones or a real subwoofer.
The tone gets louder as it goes lower. Is that good?
Usually the opposite. A speaker pushed below its limit distorts, and distortion adds harmonics that your ear registers as extra loudness. If a note suddenly seems louder or rougher as it descends, turn it down — that is the driver struggling.
Something rattles at one particular frequency.
You have found a resonance. In a car that is usually a loose trim panel; in a room it is a window or a shelf; in a speaker it may be a loose driver screw. The frequency read-out tells you exactly where it happens.
Is the Bass Test free?
Free, unlimited, and no email address required. You can use it a hundred times a day and nothing changes.
Is what I paste into the Bass Test stored?
No. The Bass Test runs entirely in your browser using JavaScript. Your input never reaches inputtesthub.com or any third party — open your browser's Network tab while you use it and you will see no request go out.
What problem does the Bass Test solve?
The jobs it is built for: finding the real low-frequency limit of a speaker or headphone. Checking a subwoofer reaches the depth it claims. Finding buzzes and rattles in a speaker cabinet or a car door panel. It is built for exactly those cases rather than being a general-purpose tool with this bolted on.
Is there a catch?
Start with the volume low and raise it slowly. Sustained pure tones are far more damaging to hearing than music at the same apparent loudness, and asking a small speaker to reproduce very low or very high frequencies at volume can damage the driver. Very low frequencies at volume are the fastest way to destroy a small speaker, because the cone travels much further than it does for music.
What figures does the Bass Test work from?
Deepest audible bass is about 20 Hz. Typical laptop speaker is nothing useful below 150 Hz. Good bookshelf speaker is down to about 50 Hz. These are printed on the page itself, so you do not have to take them on trust.
Do I need to install anything to run this test?
No installation, no extension and no driver. The Bass Test uses the browser's own device APIs and begins as soon as the page loads, so there is nothing to press first. Press Reset at any point to start over with a clean slate.
