- 2.25-inch LCD Screen with Backlight: This TS-501B sound level meter is measured noise levels are expressed in decibels and displayed on the 2.25-inch LCD screen, it easy to read on a big display design. Long press the backlight button to turn on a backlight, making it easy to view even in dim light
- Decibel Meter with A/C Weighting: TopTes TS-501B decibel meter uses a precise condenser microphone to capture sound. It’s equipped with A-weighting and C-weighting facilities that measure noise levels from 30 to 130 dB with an accuracy of 1.5 dB, Frequency from 30 to 8000Hz. Perfect for monitoring noise levels in communities, home theaters, audio systems, automobiles, workshops, schools, offices, factories
- MAX/MIN Measurement: The sound pressure level (SPL) meter has Max or Min measurement values to represent the maximum/minimum (high/low peak) value of the sound produced within a certain time, and the data hold function can freeze the current reading based on the sound measurement according to individual needs
- Easy Use and Feature Packed: The non-slip side design ensures that the portable noise meter fits easily in the hand. TS-501B SPL meter is a battery-operated noise meter that comes with three durable batteries and has an automatic power off function to extend battery life.

Select a product to estimate shipping.The TS-501B sound level meter, with weighting, ranges from 30 to 130 dB. In a quiet environment, it reads between 30 and 45 dB.
The SPL meter TS-501B has a low battery reminder function to know when the battery needs to be replaced.
The TS-501B sound level meter has a data hold function that can freeze readings.
The TS-501B decibel meter can record the maximum and minimum values of sound over a period of time.
Fast weighting(125 ms) is approximate to the ears’ time response.
Slow weighting(1 s) is used to indicate the average level of fluctuating noise.
Why doesn’t the TS-501B show 0 dB in a quiet environment?
The TS-501B measures from 30–130 dB and does not start at 0 dB. When sound levels are below 30 dB, it displays “UL” (Under Limit). In a quiet environment, it reads between 30 and 45 dB.
What scenarios are sound level meters usually used for?
Sound level meters are often used for measuring community or environmental noise; Use for measuring noise produced by machinery in industries; Use for calibrating audio equipment at concerts or for personal reasons.
What is the difference between A Frequency Weighting and C Frequency Weighting?
The A-weighting adjusts the sound pressure level readings to reflect the sensitivity of the human ear and is used for hearing damage risk measurements.
The C-Weighting is used for Peak measurements and also in some entertainment noise measurements.
What is the difference MAX/MIN Value between A-Weighting and C-Weighting?
MAX/MIN Value of A-Weighting is Lmax/Lmin (the highest and lowest values measured by the sound level meter over a given period of time.);
MAX/MIN Value of C-Weighting is Lpeak (the max/min value of the absolute instantaneous sound pressure).
Decibel Levels: Typical Scenarios
30-40 dB: Library, bedroom.
50-60 dB: Restaurant, café.
70-80 dB: City roads, factory machinery.
90-100 dB: Rock concert.
110-130 dB: Jet airplanes, front row at a concert.
