Introduction

SC42001Building acoustics measurement, sound insulation testingIn the middle,Sound insulation testing, sound insulation equipmentSC420hostIt is a high-performance device1 Sound level meter and spectrum analyzer, according toIEC 61672

standard design Designed ergonomically and equipped with * and rich expansion functions

including :1/1Octave band function,1/3Octave band analysis function,FFT Analysis function, reverberation

Time analysis function, etc.

Specially designed sound recording function that can record sound during measurement

Enable testers to record and annotate speech, expandablemicroSDCard will make

SC420It can store a large amount of data without worrying about insufficient memory.

SC420ofFunction, can easily achieve automatic instrument startup andStop measuring data, users can achieve this function through a timer or external input

Sound insulation testing, sound insulation equipmentTest function(Mainly based on the following standards)

《ISO140-3 (Corresponding to Chinese standardsGB19889.3-2005) :Laboratory measurement of airborne sound insulation of building components

《ISO140-4 (Corresponding to Chinese standardsGB19889.4-2005) :On site measurement of airborne sound insulation between rooms

《ISO140-5(Corresponding to Chinese standardsGB 19889.5-2005):On site measurement of external wall components and external wall air sound insulation

《ISO140-6(Corresponding to Chinese standardsGB 19889.6-2005):Laboratory measurement of sound insulation caused by floor impact

《ISO140-7(Corresponding to Chinese standardsGB19889.7-2005):On site measurement of sound insulation caused by floor impact

CMA Test Wizard Software

CMAThe software isCESVAThe launched testing wizard software can complete different types of sound insulationmeasureTry.

Only three steps are needed to complete the sound insulation test

1Set up test files, select test points, and check equipment testing locations

2According to the software wizard, the Bluetooth wireless module will automatically control the start and end of each component using software instructions,

3， 利用CISSoftware automatically generates reports

This software supports multi-channel input

CIS data analysis software

CISThe software has * calculation and analysis functions, and can generate reports according to standardsISO140,ISO717,ISO3382Test building air sound insulation, floor impact sound insulation, reverberation time, etc.comply withISO14-3~ISO140-8Laboratory and on-site method testing.

The reverberation time can be manually adjusted

Both data and graphs can be edited again, and reports can be printed directly or saved asPDFOr image format

1/1、1/3Octave Analysis

CESVA Insulation Studio（CISSoftware)

It is a building sound insulation testing software that automatically calculates and analyzes test results and generates reports that meet the standardsISO 140 and ISO 717,.Can test building sound insulation, floor impact sound insulation, reverberation time, etc.

according to the standard(ISO 140-3 to ISO 140-8)Generate relevant reports. This program automatically creates test reports and quickly retrieves them fromCESVA SC260, SC310andSC420Download data. The program can also manually input data or import copied data, etc.

The test data can be freely edited and modified, including images and data formats. The composite testing interface allows real-time observation of the testing status and timely detection of errors. The reverberation curve can be manually adjusted and re fitted. The generated report can be stored asPDForRTFandEMFImage file.

Compliant with standards:

ISO140-3, ISO 140-4, ISO 140-5, ISO 140-6, ISO 140-7, ISO 140-8, ISO 717-1/and ISO 717-2/ USA-ASTM
