Strong match

Who this is for

  • Setting stage volume limits before a venue complains
  • Checking rehearsal room levels to protect hearing
  • Verifying PA output during system tuning

Consider the trade-offs

When to look elsewhere

  • Guitarists shopping for a pedal — this makes no sound
  • Certified compliance measurement requiring a calibrated Type 1 meter
  • Anyone wanting a tuner, metronome, or audio interface

What matters in use

The specifications, translated

Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.

Detail 01

SPL meter, not an audio effect

It measures loudness in decibels. Nothing plugs through it and it produces no signal.

Detail 02

Handheld form factor

Walk the room and take readings at the mix position, the front row, and the stage.

Detail 03

Reads sound pressure level

Gives a number you can act on when a room or venue enforces a dB ceiling.

Detail 04

Price around $160

Sits above phone-app accuracy and below lab-grade meters used for legal noise reporting.

Final check

Know before you order

  1. 01Confirm the meter ships with batteries before your first session
  2. 02A tripod mount helps for fixed-position readings during PA tuning
  3. 03Not a substitute for a certified meter in legal noise disputes

Product questions

Before you decide

Straight answers to the questions shoppers most often ask about this product.

01Is this a guitar pedal?

No. Despite how it may be filed, this is a sound level meter. It measures how loud a room is in decibels and does not process audio.

02Can I use it to set stage volume?

Yes. Take readings at the mix position and on stage, then set a ceiling everyone plays under.

03Is it better than a phone app?

A dedicated meter uses a purpose-built microphone element rather than a phone mic tuned for voice, so readings are more consistent.

04Does it work for measuring room acoustics?

It reads level, not frequency response or decay time. For acoustic treatment work you need a measurement mic and analysis software.
