The basic setup
Home recording has never been more accessible. At its core you need a computer running a DAW (digital audio workstation — the recording software), an audio interface to get sound in and out, a microphone or instrument connection, and headphones.
Start simple
Do not buy everything at once. A modest interface, one decent mic and free or affordable software are enough to make real recordings. Learn to record and arrange one track well before chasing gear.
The volumes a home setup can actually reach
It is easy to assume hearing-safety guidance is a factory-floor concern that does not apply to a bedroom studio, but the numbers do not care where the sound comes from. The CDC’s National Institute for Occupational Safety and Health (NIOSH) sets its recommended exposure limit at 85 A-weighted decibels (dBA) averaged over an eight-hour day, with a 3 dBA exchange rate — for every 3 dB the level climbs, NIOSH recommends cutting the safe exposure time in half.
NIOSH’s own list of everyday sources sitting at or above that threshold includes printing presses, lawnmowers, vacuums and power tools around 85–90 dBA, and sources at 95 dBA or higher including bulldozers, chain saws, and — a genuinely relevant comparison for a home studio — bars, nightclubs and large sporting events. A pair of monitors or headphones pushed to that kind of loudness for a long mixing session sits in the same range.
What the exchange rate does to a long session
Because the exchange rate is 3 dB, the safe-listening budget shrinks fast as the level climbs. Starting from NIOSH’s 85 dBA/8-hour reference point, each further 3 dB roughly halves the allowed time: 88 dBA works out to about 4 hours, 91 dBA to about 2, 94 dBA to about 1 — a much steeper curve than “just a bit louder” suggests, and one that catches up with a long session faster than it feels like it should.
NIOSH also names practical warning signs worth watching for during a session: ringing ears, sounds seeming dull or flat once you step away from the speakers, and catching yourself nudging a personal device’s volume up as the session goes on — all signs the ear has been asked to work harder than the exposure budget allows.
Working the halving forward from the 85 dBA/8-hour baseline: 85 dBA ≈ 8 hours, 88 ≈ 4, 91 ≈ 2, 94 ≈ 1, 97 ≈ 30 minutes, 100 ≈ 15 minutes — six steps of 3 dB, each one halving the clock.
Then build skills
- Learn your DAW's basics — record, edit, arrange.
- Get clean recordings at the source (good input, quiet room).
- Add mixing and effects gradually.
- Reference songs you like to judge your sound.
Check a monitoring level against the exposure budget
Enter roughly how loud your monitors or headphones are running, and this applies NIOSH’s reference figure and exchange rate. Nothing is stored or sent anywhere.
Built directly from NIOSH’s 85 dBA/8-hour reference and 3 dB exchange rate — a guide for pacing a session, not a hearing-health diagnosis. If your ears ring or sound feels muffled afterward, that is your cue regardless of what any calculator says.

The halving sequence and the calculator above apply NIOSH’s stated exchange rate arithmetically; neither is medical advice, and a clinician or audiologist is the right call for a specific hearing concern.
Common questions
What is a DAW?
A digital audio workstation — the software you record, edit and mix in. Many good free and paid options exist.
Do I need expensive gear to start?
No — a basic interface, one mic and free software can make genuinely good recordings. Skills matter more than gear.
Why do my recordings sound thin?
Often the room, mic placement or input level. A clean, strong source recording helps more than plugins.
