10 Best Sound Decibel Meters 2025 in the United States

The TopTes TS-501B Sound Level Meter is designed to measure noise levels accurately within a range of 30 to 130 dB. Its key strength lies in its dual A/C weighting options, making it versatile for different types of sound measurements. The device boasts an impressive accuracy of ±1.5 dB and a frequency range from 30 to 8000Hz, which is suitable for a wide variety of environments including homes, factories, and schools. The 2.25-inch backlit LCD screen ensures that readings are easy to view even in poor lighting conditions. Furthermore, the MAX/MIN and Data Hold functions allow users to capture and freeze specific sound levels, adding to its practicality.

The meter is also user-friendly with a non-slip design, battery operation, and an auto power-off feature to conserve battery life. It comes with three AAA batteries, a carry case, and a user manual for convenience. However, there are a few drawbacks. The device is relatively basic, lacking advanced features found in higher-end models, such as connectivity to other devices or data logging capabilities. Additionally, the build quality, although functional, may not be as robust as some professional-grade meters.

Despite these limitations, the TopTes TS-501B offers good value for everyday use, especially for those needing a reliable and straightforward decibel meter for monitoring noise levels in various environments.

The Tadeto Digital Sound Level Meter offers a reliable range from 30dB to 130dB and is highly accurate with a ±2.0 dB margin of error. This makes it suitable for a variety of environments, including homes, factories, and schools. It features A/C weighted measurements, which are beneficial for both low-intensity ambient noise and high-intensity industrial noise, respectively.

The fast and slow response time settings add flexibility, making it easier to measure both stable and fluctuating noise levels accurately. The meter boasts a clear 4-digit LCD display with backlight, which aids in readability in darker conditions. However, the constant need for AAA batteries (though included) might be a slight inconvenience for some users.

The device is lightweight and portable, making it convenient to carry around for different applications. While its plastic build might not seem very rugged, it should suffice for general usage. Given its strong performance and user-friendly interface, it is a great option for those needing precise sound level measurements in varied settings.

The Extech SL510 is a compact and lightweight sound level meter designed for basic noise measurement tasks. It covers a measurement range from 35 to 130 dB, which suits many common environments like workplaces or home noise checks. Its ±1 dB accuracy meets Class 2 standards, offering reliable readings for general use, though it may not be precise enough for professional or legal sound assessments.

The meter includes both A and C frequency weighting, allowing you to measure noise as the human ear hears it (A-weighting) or capture more low-frequency sounds (C-weighting). You can choose between fast and slow response times, which helps adapt measurements to different types of noise events. The backlit LCD screen is helpful for reading results in dim settings. Additional functions like Data Hold and Min/Max make it easier to record and review sound levels without constantly watching the display.

Powered by included AAA batteries, the SL510 is ready to use out of the box. This meter is a solid choice for hobbyists, students, or anyone needing a straightforward and portable device for general sound level checking, while those requiring highly accurate or certified measurements might want to consider higher-end models.
