Low-frequency noise
How to document low-frequency noise and bass vibration
Low-frequency noise can feel like a hum, rumble, thump, or vibration. It may not sound loud on a phone meter, so the pattern, location, duration, and physical effect are especially important.
Describe what you hear and feel
Low-frequency noise is often hard to explain because it may travel through walls, floors, pipes, or structural elements. In your log, describe both the sound and the sensation.
- Sound words: hum, drone, rumble, bass, thump, pulsing, engine-like noise.
- Sensation words: vibration, pressure, shaking, resonance, bed or desk movement.
- Location: bedroom, ceiling, floor, shared wall, window, bathroom pipe, HVAC area.
- Pattern: continuous, intermittent, rhythmic, nighttime-only, weekday-only, weather-related.
Why dB readings may not tell the whole story
Many phone and browser measurements are useful for comparing changes in your own environment, but they are not certified sound level measurements. Low-frequency vibration may also be underrepresented by a simple dB-like reading. Treat the reading as a supporting reference, not the whole case.
A better low-frequency noise log
- Record the start and end time of each hum, rumble, or vibration event.
- Note the room and exact spot where it is strongest.
- Write down whether the vibration affects sleep, work, calls, or rest.
- Take a screenshot of the monitor when the pattern changes.
- Compare the same room at quiet times and noisy times.
Use Anti Noise Assistant
Anti Noise Assistant can help you watch dB-like changes while you build a timestamped log of low-frequency noise, bass vibration, and recurring apartment resonance.
