Tapping Machine – Model BAS004 Tapping Machine – Model BAS004 Impact Noise Excitation for Sound Insulation Measurement in Buildings Maintenance Free Design Battery Operated Remote Control Included Building Acoustics Measuring Impact Sound Level Measuring Airborne Sound Insulation Measuring Sound Transmission Loss The BAS0041 is used to simulate foot fall noise in a manner that is well controlled and reproducible so that measured results can be replicated and compared with other measurements. Unique to the BAS004 is an innovative method for raising the five “hammers” using an electromagnetic field rather than the traditional motor, gears and cam. This eliminates unwanted vibration and maintenance associated with a motor, gears and cam while producing better measurements with a virtually maintenance free product. The BAS004 also features a stiff internal frame to keep the product rigid and structurally stable. It also incorporates feet that rotate underneath in order to make it smaller for transportation and packaging. Combine the BAS004 with the other Larson Davis products for building acoustics to create your measuring solution. Backed by our excellent technical support and our service and calibration facilities, the BAS004 makes an excellent choice for your tapping machine needs.
