This lightweight meter accurately monitors sound levels in a range from 40 to 130 decibels. It displays results in the large LCD display in two different ways, either by number or a fast-responding analog bar graph. Records sound levels from 40 to 130 decibels. Precise readings with +/-2 dB accuracy and 0.1 dB resolution. Dimensions: 9 x 2.2 x 1.7 inch (230 x 57 x 44 mm). Weight: 5.6 oz (160 g). Professional Digital Sound Level Meter Accurately measures sound levels Wherever you need to monitor sound levels, the Extech sound meter will do the job. The meter utilises a 1/2-inch electric condenser microphone to monitor sound levels from 40 to 130 decibels at an accuracy of +/-2 dB with a 0.1 dB resolution. A windscreen is included to prevent distortion in the readings. The unit also mounts on a tripod, providing convenient hands-free readings. Large LCD screen with dual reading displays The large, 2,000-count LCD display gives readings in large, clear numbers. At the same time, it shows the sound level readings using a fast-responding analog bar graph with a 50-decibel range that updates every 40 milliseconds for viewing varying trends. The unit has AC analog output and records maximum/minimum values over time. Compact, lightweight design The Extech sound meter weighs less than 6 ounces and is designed to fit comfortably in the palm of your hand. The meter is white with a black-framed screen and black buttons. User-friendly settings Choose between either A or C weighting, auto or manual ranging. Other useful features include auto power-off, maximum hold functions and fast/slow response time. Record sound values over time to track sound changes.

Instal audio or alarm systems By monitoring noise levels during the installation of audio or alarm systems, future users will be protected from excessive noise. Review: Speakers sound better after using this - Has made my movie listening far better after using this to dial in my 5.1.4 Atmos setup Review: Bought to test audibility on Fire alarms and services plant. - OK its chinese, it will never be a Rhode and Schwarz but for a quick test to see that the dBa of the alarms is in the right ball park, it does it quite well. Nicely built. Could do with a protective case with it and for the money, even a slip cover would be good. Fortunately I had the box my previous meter came in that was replaced with this one after it died. Overall a reasonable tool ## Features - 2dB accuracy with 0.1dB resolution - A+C weighting - AC analog output - Record Max/Min values over time - Utilizes 0.5"(12.7mm) electret condenser microphone ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000EWY67W | | Amperage | 300 Milliamps | | Audio Output Effects | Multi-Effect | | Best Sellers Rank | 105,283 in Business, Industry & Science ( See Top 100 in Business, Industry & Science ) 4,649 in Scanners & Testers 11,846 in Test & Measurement 42,086 in Electrical | | Brand | Extech | | Brand Name | Extech | | Colour | White | | Connector Type | 3.5mm Audio Jack | | Controls Type | Knob | | Country of Origin | China | | Customer Reviews | 4.5 out of 5 stars 253 Reviews | | Global Trade Identification Number | 00793950407301 | | Hardware Interface | 3.5mm Audio | | Included Components | Microphone wind screen, four AAA batteries | | Item Dimensions | 22.9 x 4.3 x 5.6 centimetres | | Item Dimensions L x W x H | 22.9L x 4.3W x 5.6H centimetres | | Manufacturer | Extech | | Manufacturer Part Number | 407730 | | Model Name | 407730 Digital Sound Level Meter | | Model Number | 407730 | | Power Source | Battery Powered | | Product dimensions | 22.9L x 4.3W x 5.6H centimetres | | Signal Format | Analog | | Style | Digital | | UPC | 793950407301 | | Unit Count | 1 Count | | Voltage | 9 Volts | ## Product Details - **Brand:** Extech - **Style:** Digital - **Colour:** White - **Product dimensions:** 22.9L x 4.3W x 5.6H centimetres - **Voltage:** 9 Volts ## Images ![Extech Instruments 407730 Digital Sound Level Meter - Image 1](https://m.media-amazon.com/images/I/717vH6r1VdL.jpg) ![Extech Instruments 407730 Digital Sound Level Meter - Image 2](https://m.media-amazon.com/images/I/81v-hXq6y0L.jpg) ![Extech Instruments 407730 Digital Sound Level Meter - Image 3](https://m.media-amazon.com/images/I/614WslPeFoL.jpg) ![Extech Instruments 407730 Digital Sound Level Meter - Image 4](https://m.media-amazon.com/images/I/71vx+UjplkL.jpg) ![Extech Instruments 407730 Digital Sound Level Meter - Image 5](https://m.media-amazon.com/images/I/61UoKClWgiL.jpg) ## Available Options This product comes in different **Style** options. ## Questions & Answers **Q: Is a protective case supplied with this meter?** A: Hello, no.

Nicely built. Could do with a protective case with it and for the money, even a slip cover would be good. Fortunately I had the box my previous meter came in that was replaced with this one after it died. Overall a reasonable tool ### ⭐ Failed badly on frequency response tests, insensitive *by L***D on 27 November 2012* I tested this thoroughly in our microphone calibration room alongside our reference mic. Calibration at 1kHz 90dB SPL was spot on - it read 90.0! However, this is only part of the story. Tests at ten frequencies revealed that the A-weighting is nowhere near correct. Errors were: 50Hz +16dB, 100Hz +0.3dB, 200Hz +1.6, 2kHz +0.3 10kHz +13.5dB!! 12.5kHz +7.3dB. The gross errors at 50Hz and 10kHz are totally unacceptable and massively outside the standard specification. The peak at 10kHz will make it read very high on noise sources with high frequency content. Note also that the minimum reading is 40dBA which makes it useless for measuring noise on fridges, air conditioning etc which normally fall in the range 20 - 35dBA. A shame as the analog bar is a nice feature. ## Frequently Bought Together - Extech 407730 Digital Sound Level Meter 40-130dB - Extech LT300 Light Meter --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.de/products/51926108-extech-instruments-407730-digital-sound-level-meter](https://www.desertcart.de/products/51926108-extech-instruments-407730-digital-sound-level-meter) --- *Product available on Desertcart Germany* *Store origin: DE* *Last updated: 2026-06-25*
