RGSRResonant Geophysical Systems Research

Sound in air. Shaking in layered ground.

Every curve was computed by CORE's simulation engines and published as numbers. Change a case to see how the physics responds.

SimulatedNot a measurement. Material values are typical, not data from any real site.

Speed of sound against temperature

Figure 1. Sea-level pressure; dry air, 50 % and 100 % RH, 0–30 °C.

Sound lost per 100 m, by pitch

Methods: speed of sound after Cramer (1993); atmospheric absorption after ISO 9613-1.
