Loudmark Decibel Meter

Measure the quiet before you move in. Loudmark is a decibel meter for comparing places: the apartment you're viewing, your bedroom against the living room, the same street at 3 pm and at 11 pm. It shows the checks side by side and never records a sound.

Check a place

Name a place, stand where you would sleep or work, and run a 30-second or one-minute check. The sound level meter keeps the check with that place and the time of day.

The background noise level, not only the peaks

Each check gives the background level (what is left when nothing in particular happens), the average, the peaks and the maximum in decibels. The background tells you whether a room is quiet at night, which a plain dB meter reading at one moment can't.

Side by side

Put two checks next to each other on one dB scale. The quieter place is marked, so the difference in room noise shows at a glance.

Times of day

A place's checks fall into morning, afternoon, evening and night, so "quiet in the afternoon, loud at night" shows up on its own.

Mark what you hear

While measuring, tap Train, Traffic, Neighbors, Voices, TV or a label of your own, and a flag lands on the live noise graph at that moment.

The noise meter

Loudmark is also a plain sound level meter and noise meter. A clear dial with the live noise level in dB; min, average and max; a 60-second graph; a big number you can read across a room; and everyday sounds to compare with. You can match it to a meter you trust, for free.

Nothing recorded

The microphone gives a number on the phone and the sound is gone at once. No audio is saved or sent. The microphone runs only while Loudmark is on screen. Places and checks stay on your phone: no account, no ads, no tracking, no location.

Good for

• Viewing an apartment or a house: check the bedroom at night before you sign

• Picking the quietest bedroom, or a hotel room away from the street

• Finding a quiet place to work, study or read

• Seeing how loud traffic, trains or neighbors get, and at what time of day

• A quick noise level reading anywhere, like any sound meter
