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...

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...

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...

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...

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...

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...

6 • The World Through Sound: Acoustic Medium

Welcome to the sixth installment of The World Through Sound. Last time we discussed one of the most popular units for measuring sound, the decibel , and gave a few rules of thumb to help even a non-scientist make sense of decibel values. In this edition instead of...

5 • The World Through Sound: Decibels

Welcome to the fifth installment of The World Through Sound. Last time, we discussed the concepts of equilibrium and acoustic pressure, and how almost any variation around equilibrium can bear a striking resemblance to the behavior of sound. Today, we are going to...

4 • The World Through Sound: Acoustic Pressure

Welcome to the fourth installment of The World Through Sound. In previous articles we discussed properties of sound, including sound speed, and wavelength. Today, we are going to take a step back and consider sound on a more fundamental level. We are going to discuss...
