How to choose a sound meter

Selecting the best sound meter starts with understanding your primary goal. Is it for official noise compliance at work, long-term environmental monitoring, or checking if your home theater is too loud for the neighbors? The key specs in the listings will point you in the right direction.

First, consider the measurement range and accuracy. Professional applications often require meters that meet specific standards like IEC 61672 Class 1 or 2, which guarantee a certain level of accuracy across a defined range. For home use, a wider range (e.g., starting at 30 dB) lets you measure very quiet rooms, while a higher top end (130 dB or more) is needed for loud machinery or events. Learn more about how decibels work in our guide to headphone sensitivity.

What to look for

  • Standards Compliance: Look for “IEC 61672 Class 2” or “ANSI Type 2” if you need measurements for workplace safety (OSHA) or official reports.
  • Weighting Modes: A-weighting (dBA) mimics human hearing for environmental noise. C-weighting (dBC) is for measuring peak, industrial sounds. Some meters offer both.
  • Data Capabilities: Do you need a spot reading or a log over time? “Data logging” meters save readings internally or to a memory card. Some connect via USB or Bluetooth to software.
  • Frequency Analysis: For troubleshooting noise sources, features like “octave band analysis” or “FFT” break down which frequencies are present.

Finally, think about usability. A backlit screen is essential for low-light conditions, while a simple analog bar graph can make fluctuating levels easier to track visually. For outdoor use, a windscreen or “windproof sponge” is crucial. Always follow the manufacturer’s manual for proper use and safety.

FAQ

What’s the difference between dBA and dBC?

dBA and dBC are different “weightings” applied to the raw sound measurement. A-weighting (dBA) reduces the importance of very low and very high frequencies to approximate how the human ear hears at normal conversation levels. It’s used for environmental noise, workplace safety, and most general purposes. C-weighting (dBC) applies less reduction, giving a better representation of the total sound pressure, which is important for measuring peak levels from machinery, explosions, or loud music. Many meters offer both modes.

Do I need a calibrated sound meter?

If you are taking measurements for legal, regulatory, or official compliance purposes (like OSHA workplace noise assessments), you typically need a meter that meets a recognized standard (like IEC 61672 Class 2) and comes with a valid calibration certificate. For personal, educational, or non-critical home use, a non-calibrated meter may be sufficient to give you a good estimate of noise levels.

Can I use a smartphone app as a sound meter?

While smartphone apps can measure sound, their accuracy is limited by the phone’s built-in microphone, which is not designed for precision measurement. They are not calibrated to international standards. For casual curiosity, an app might be okay, but for any serious purpose—especially regarding hearing safety, legal evidence, or product testing—a dedicated sound level meter is the appropriate tool. For more on protecting your hearing, see the NIDCD.

What does “Fast” and “Slow” response mean on a sound meter?

These are time weighting settings. “Fast” response (usually 125 milliseconds) allows the meter to react quickly to sudden changes in noise, useful for measuring impulsive sounds like hammering or car horns. “Slow” response (usually 1 second) averages the sound level over a longer period, providing a more stable reading for steady-state noise like the hum of an air conditioner or background traffic. Many meters let you switch between them.
