Digital Sound Meter
Product Code : LSK-PL-10373
Digital Sound Meter (SKU LSK-PL-10373) is a pocket-sized sound level meter that reads from 30 to 130 dB with A and C frequency weighting. Teachers use it to put numbers on loudness and noise in science lessons, and it also serves project work and simple noise surveys. Science Lab Supplies supplies the meter from Ambala, India to schools, colleges, training institutes, tender contractors and distributors.
Specifications
The meter has a plastic casing, an LED backlit digital display and a measuring range of 30.0–130.0 dB. Response can be switched between fast and slow, and A or C weighting can be selected. It is pocket sized, 210 mm long and 32 mm deep, and comes with a carry case.

Applications and Experiments for the Digital Sound Meter
The meter turns loudness into a measured sound level in decibels, so students can compare sources, distances and rooms instead of guessing. It supports the sound chapters of CBSE/NCERT Class 8 and Class 9 science, wave topics in Class 11 physics, and noise measurement exercises in environmental science courses.
- Class 8–9 science: loudness, the decibel scale and noise pollution.
- Class 11 physics: showing how sound level falls as distance from a source increases.
- Environmental science and engineering labs: short noise surveys of classrooms, roads or workshops.
Standard Scope of Supply
Each Digital Sound Meter is supplied in its carry case, with the plastic-cased meter and backlit display described above. No further accessories are listed as standard; if you need anything extra for your practicals, it will appear as a separate line on the quotation.

Frequently Asked Questions
What range does the Digital Sound Meter measure?
It measures sound levels from 30.0 dB to 130.0 dB, with A or C weighting and a fast or slow response selected by the user.
What is the difference between A and C weighting?
A weighting follows the ear's reduced sensitivity to low and very high frequencies and is used for general noise readings; C weighting is flatter and is used for louder sounds and low-frequency content.
Who supplies the Digital Sound Meter?
The meter is supplied by Science Lab Supplies from Ambala, India. It can be dispatched together with the other laboratory items on your quotation.
Is a carry case included?
Yes. The meter is supplied with a carry case, which keeps it protected when it is taken outside the laboratory for surveys.
