Problems of Impact Testing of Floors
The result of impact testing of floors depends – in contrast to the air-borne-sound-testing – on the internal impedance of the exciter. Only if the impedance of the floor is much larger we may even infer from air-borne-sound measurements the impact-reaction. But with elastic layer the impact test results depend on the internal impedance and therefore on the choice of the type of excitation. In comparison with footfalls the tapping machine results give too high levels below bare floors. This could be eliminated by making use of hammers with rubber coating as already alternatively recommended in ISO R 140. – Another difficulty results from the nonlinear behaviour of elastic layers. This could be overcome by decreasing the momentum-level by 5 dB. – It has also been proposed to take the special impulse-character of footfalls into account by measuring the levels of masking noise, and to substitute this difficult testing by measuring peak levels. The last method also suggests measuring the peaks of the structure-borne-sound in the ceiling immediately.
