In acoustics he studied the propagation of sound and musical consonance and dissonance . 在聲學(xué)中,他研究了聲的傳播和音樂的和諧與不和諧。
Propagation of sound 聲音的傳播
In 1981 he showed that there is a close analogy between the propagation of sound in a moving fluid and that of light in a curved spacetime 1981年,他證明了聲波在流體中的傳播,和光在彎曲空間中的傳播有極為接近的類比。
Atmospheric acoustics is the study of propagation of sound waves in the atmosphere . listed in it is the study of infra - sonics , which focuses on inaudible , low - frequency sounds 研究聲音在大氣中傳播特性的科學(xué)稱為大氣聲學(xué),當(dāng)中的次聲學(xué)便是專注于人耳無法聽到的低頻聲音。
