What is the difference between an echo and a reverberation?

How do you calculate the best note to whistle in a toilet?

Where do you best place microphones for that perfect recording?

In this fascinating little book, musician Steve Marshall explores the subject of acoustics.

From decibels to dolphins, stereo to surround, this book will appeal to singers, musicians, architects, biologists, and anyone who ever wanted to know more about the wonderful world of sound.

What is the difference between an echo and a reverberation?

An echo is a sound that is produced by the reflection of a sound wave off a surface. It is created when the sound wave hits a surface and bounces back, creating a new wave that is identical to the original wave but with a slight delay. The delay is caused by the time it takes for the sound wave to travel from the source to the surface and back. The distance between the source and the surface, as well as the properties of the surface, can affect the quality of the echo. For example, a flat surface will produce a clearer echo than a rough surface. A reverberation is a sound that is produced by the reflection of multiple sound waves off surfaces. It is created when a sound wave hits a surface and bounces back, creating a series of reflections that continue to build up over time. The reflections are caused by the time it takes for the sound wave to travel from the source to the surface and back, as well as the properties of the surface. The length of time that the reflections continue to build up is determined by the size of the space and the absorption of the surfaces. Reverberations can be used to create a sense of depth and space in a recording or live performance. They can also be used to create a sense of atmosphere or mood. To calculate the best note to whistle in a toilet, you can use a simple formula that takes into account the size and shape of the space. The formula is: f = (v / d) * t, where f is the frequency of the whistle, v is the speed of sound, d is the diameter of the toilet, and t is the time it takes for the sound wave to travel from the source to the surface and back. For example, if you want to whistle at a frequency of 100 Hz, you would use the following formula: f = (100 / 0.04) * 0.015 = 6,666.67 Hz. To get the best recording quality, you should place microphones in a variety of locations around the space. The most important microphone is the main microphone, which should be placed in the center of the space. Other microphones can be placed around the space to capture different aspects of the sound. For example, you can place microphones on the walls, ceiling, and floor to capture the sound of the toilet flushing, the sound of the water flowing, and the sound of the air moving. You can also place microphones on the toilet seat and lid to capture the sound of the user's voice. When placing microphones, it is important to consider the following: the distance between the microphones, the angle of the microphones, and the sensitivity of the microphones. The distance between the microphones should be close enough to capture the sound without creating too much noise, but not so close that the microphones pick up each other's sound. The angle of the microphones should be such that they capture the sound in the most direct way possible. The sensitivity of the microphones should be such that they can capture the faintest sound without creating too much noise. In conclusion, an echo is a sound that is produced by the reflection of a sound wave off a surface, while a reverberation is a sound that is produced by the reflection of multiple sound waves off surfaces. To calculate the best note to whistle in a toilet, you can use a simple formula that takes into account the size and shape of the space. To get the best recording quality, you should place microphones in a variety of locations around the space, including the main microphone, the walls, ceiling, and floor, as well as the toilet seat and lid. When placing microphones, it is important to consider the distance between the microphones, the angle of the microphones, and the sensitivity of the microphones.
