A good tool for building acoustic testing-SVLab 239 Standard Tapping Machine



The standard impactor (also known as the standard impactor or floor impactor) is a professional measurement tool used in laboratory and on-site measurements of floor impact sound insulation performance. It is also the main artificial sound source used in on-site measurement of sound insulation performance of sound enclosures. part. It consists of 5 impact hammers. The free falling motion of each impact hammer acts on the test surface such as the floor slab within a specified time interval to generate impact sound.

 


 

 
In building acoustics testing, the selection and use of test equipment is crucial to the accuracy and reliability of test results. The SVLab 239 standard impactor is an excellent test device that can provide accurate impact response measurements and help us better understand the acoustic properties of buildings.
 


First, let's take a look at the structure of the SVLab 239 standard impactor. The standard impactor is mounted on three height-adjustable rubber support feet via an aluminum frame. An internal camshaft drives five drop weights of 500 grams each, spaced 10 centimeters apart. The hammer mass, impact height and distance between hammers of our SVLab 239 standard impactor are all designed in strict accordance with the specifications. After operation, it can produce a precise impact sound source

02 Building floor sound insulation measurement tool

The SVLab 239 standard impactor is an impact sound source suitable for sound insulation measurement of building floors. It uses wireless radio frequency technology to achieve remote control and easily penetrate common walls and ceilings. The integrated structural design ensures strength while also achieving lightweight, supports battery and AC power supply, and is suitable for a variety of measurement scenarios.

Using the SVLab 239 standard impactor for building acoustics testing can help us understand the building's sound insulation performance, acoustic quality and airborne sound insulation performance. This is of great significance to ensure that the acoustic performance of the building meets the requirements and to improve the quality of the living and working environment.
