sound measurement

2 Progress driven by research experience We have a highly qualified team of professionals, made up of specialist engineers from the fields of acoustics, mechanics, electronics, computing and electromagnetic compatibility. CESVA participates on a variety of national and international committees for the creation and revision of regulations and standards. This has enabled us to become a pioneer in the sector. innovation “Single measurement range”, “simultaneous measurement of all functions”, “Bluetooth technology in insulation measurements” and “sound level meters with measurement protocols”...

9 BEFORE: Imports drawings, selects measurement points and verifies contour conditions. DURING: Automatically manages devices using Bluetooth® with a step-by-step guide to measurement. Indicates the position of equipment, starting/stopping of noise sources, and gives real-time reception and verification of the measurements taken by sound level meters. AFTER: Direct interaction with CIS in order to receive the final report on site. With this software, a number of CESVA sound level meter analysers can be converted into a wireless multichannel measurement system. The system is fully...

All data is processed and uploaded to the SERDAT data server. Features • The TA024 maintains the legal metrology of the SC310 sound level meter. • Simultaneously measures the functions...

11 CSE (Capture Studio Editor) software enables data captured by Dosimeters and Spectrum Analysers (CESVA SC310, SC-30, SC160, DC112 and VC431 vibrometer) to be edited. An intuitive and user-friendly tool for the extraction or deletion of any undesired time section. Permits the re-calculation of global and spectrum values for the desired section, as well as statistical information (maximums, minimums, percentiles). The mobile communications system for CESVA equipment is based on the GSM/GPRS standard and allows communication between different CESVA instruments (sound level meters and...
