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. It can be used to put numbers on loudness and noise in science lessons and suits project work and simple noise surveys. Schools, colleges, training institutes, tender contractors and distributors obtain it through Science Lab Supplies in Ambala, India, which sources the meter and dispatches it with their other laboratory items.
Specifications
Range, weighting, response, display and size of the sound meter each take a row of the table. In short, it measures 30.0–130.0 dB with A or C weighting and a selectable fast or slow response, shows readings on an LED backlit display, sits in a plastic casing 210 mm long 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 9 science: putting numbers on reflected sound during work with the Law of Reflection of Sound Apparatus.
- Sound needs a medium: noting how the bell's sound changes outside the jar as air is removed in the Bell Jars demonstration.
- 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 LED backlit display described above. If your practicals need a sound source, a signal generator or a loudspeaker as well, each can be added as a separate line on the quotation.
Packing, MOQ and Lead Time
Whether you need one meter for the physics department or several for student groups, send the quantity and we will quote. The quotation states packing, delivery time and price, and as a physics instruments supplier in India we can add loudspeakers, microphones or tuning forks to it.
As a registered exporter with an Importer-Exporter Code, Science Lab Supplies is able to ship to buyers in Bangladesh, Zambia, Rwanda, South Africa, Qatar and Sri Lanka. For a price on sound meters, message us from the contact page or build a list in the enquiry cart; school and college bids are handled through the lab tender page.
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, so both quiet rooms and loud sources can be read.
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?
Quotations for this meter come from Science Lab Supplies in Ambala, India, which sources it and can dispatch it for your laboratory together with the other items on the same order, packed for the delivery location you give.
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 noise surveys or moved between classrooms.
