Product description

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.

  1. Precision Microphone

    The microphone of decibel meter converts the sound signal to an equivalent electrical signal.

  2. Protective Film

    With a screen protector to avoid scratches on the screen of the decibel meter during transportation.

  3. Anti-slip Design

    The durable plastic anti-slip strips on both sides of the noise meter TS-501B, increase friction.

  4. Easy to Carry

    The velvet cloth pouch with bungee cord is easy to store and protect SLP meter TS-501B.

Low Battery Indication

The SPL meter TS-501B has a low battery reminder function to know when the battery needs to be replaced.

Data Hold Function

The TS-501B sound level meter has a data hold function that can freeze readings.

Max/Min Measurement

The TS-501B decibel meter can record the maximum and minimum values of sound over a period of time.

Fast/Slow Time Weighted

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 do we need to measure noise?

    Sound level meters are commonly used to measure noise levels in people's environments and to ensure people stay within safe noise limits and protect people from hearing damage/loss.

  • 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.
