As a basic study for the method of assessing the loudness of impulsive sounds, two stages of loudness matching tests were carried out using exponentially decaying isolated impulsive sounds with narrow frequency components by changing the decaying timeconstant and carrier frequency. As a result, it was found that the total energy(the squareintegrated value of sound pressure) should be evaluated to uniformly assess the loudness of isolated impulsive sounds over a wide range of decaying characteristic. To examine the influence of waveform of impulsive sounds with loudness in detail, another experiment was made by using eight impulsive sounds with 1kHz carrier frequency and various waveforms. Consequently, it was found that the vibration of waveform is not so significant (only 2 dB at the most) for the loudness assessment.
