From the Editor

From the Editor | Arthur N. Popper   This issue continues our approach to having very diverse articles in Acoustics Today (AT). At the same time, a number of articles in this issue continue the “themes” that have been running through several earlier issues of AT. For...

Off World Sounds – Sound Files

Unaltered sound-source files that illustrate the recorded music and speech that were processed to simulate the off-world sounds. Table 1. Audio/video sound-source files 94dB Calibration “Organ” “Mars” “Titan” “Venus” Table 2. Organ music, as heard on the location...

12 • The World Through Sound: Absorption

Welcome to our final installment of The World Through Sound. Last time, we learned about linearity, non-linearity, and how linearization allows scientists to treat complicated systems like much simpler analogs through approximation. In this article, we will explore...

11 • The World Through Sound: Linearity

Welcome to another installment of The World Through Sound. Last time, we talked about reflection and refraction, and the principle of least time that governs them. This week we will discuss linearity, superposition, and how science uses approximations to make the...

10 • The World Through Sound: Refraction

Welcome to another installment of The World Through Sound. Last time, we talked about mode shapes and the blurry line between things that are discrete and distinct and things that are continuous and fluid. This time, we’ll cover reflection and refraction, and learn...

9 • The World Through Sound: Normal Modes

Welcome to another installment of The World Through Sound. Last time, we talked about resonance and why some things ring while others don’t. In this article, we will go deeper into that concept and explore normal modes, the patterns of motion that are created when...

Supplementary Text Violin Acoustics

Modelling Violin Modes Introduction In Figure S1 we first describe how the modes of the initially freely supported plates are transformed, when coupled together around their edges by the ribs, into those of the empty body shell. This relationship is of considerable...

8 • The World Through Sound: Resonance

Welcome to another installment of The World Through Sound. Last time we talked about Acoustic Impedance, and how horns are actually a kind of transformer, and operate in a way analogous to how a lever makes a large mass easier to move. In this article, we will talk...

7 • The World Through Sound: Acoustic Impedance

Welcome to another installment of The World Through Sound. Previously we learned about the acoustic medium, and how sound can even move through the seeming vacuum of space, and shape entire galactic structures in the process. Today’s article is a direct follow-up to...
