SP 95 – Impact Ball
The SP 95 impact ball is used for testing building acoustics and sound insulation in lightweight structures where a standard tapping machine (impact sound source) would produce too much impact force.
It has been designed by ISO 10140-5 and ISO 16283-2 standards. The use of the SP 95 Impact Ball is very easy: it is dropped vertically in a free fall from a height of 100 cm to the surface of the floor. In practice, SP 95 can be used to assess soft impacts related to human disturbance, such as children jumping.
The SP 95 is used for low-frequency impact noise insulation tests in the octave bands from 31.5 Hz to 500 Hz. The weight of 2.5 kg. The kit includes a comfortable carrying bag for transportation.
