Examples of earthquake sound
Time series waveform, Fourier spectrum, response spectrum, and so on, can represent the characteristics of seismic motion truly. But it is difficult for non-specialists to image behavior of the ground or buildings under earthquakes directly or clearly through these indices. Therefore more intuitive representation of seismic motion is required for making non-expert people aware the importance of disaster mitigation activity. A sound representation of seismic motion is supposed as one of solutions. Hearing sounds is more effective than viewing a waveform, Fourier spectrum, and so on, for non-specialists to understand an earthquake intuitively.
We propose a new method which transforms time series waveform of an earthquake into a sound.
Please appreciate following sounds.
