Notice: Air density ρ is not the same as air pressure p0. Air Density Calculations First, consider the ideal gas law: (1) p · V = n · R · T Density D = ρ is the number of molecules of the ideal gas in a certain volume. . (2) D = ρ = n / V By combining the previous two equations, the expression for the density D = ρ becomes: As an example, using the standard sea level conditions of P = 101325 Pa and T = 15°C, the air density at sea level, can be calculated as: QRD Diffuser Well Depth Calculator. QRD Diffuser Well Depth Calculator Welcome.
This script will calculate the well depths of a QRD (Quadratic Residue Diffuser) given a specified well width and a maximum well depth. The width and max depth should be specified in inches, with or without decimal fractions (ie 9 or 8.5 for example). This can be used as a guide for building a diffuser. The sequence of well depths shown are simply repeated over and over.

FuzzMeasure. FuzzMeasure Pro 3 delivers a comprehensive suite of features geared towards professionals in the acoustics, live sound, and recording industries.
By combining a complete toolset with an elegant yet simple user interface, FuzzMeasure Pro 3 lets you capture all the measurements you need without getting in your way. Overview FuzzMeasure Pro is an audio and acoustical measurement application used to create, produce, and analyze visually stunning graphs of your measurements. Using FuzzMeasure’s tools you can easily gather measurements of a home theatre system, recording studio, stage, auditorium, raw loudspeaker components, and more. Technology FuzzMeasure leverages many technologies found within Apple's Mac OS X Leopard operating system. ETF. Dirac. Dirac is a sophisticated tool to calculate a very wide range of acoustical parameters from impulse response measurements of an enclosure.
Through many years of development and customer feedback, Dirac has grown to support many different applications. Due to its user friendly interface it is suitable for field measurements, but it also contains many advanced features that make it useful in a laboratory or research setting. To capture an impulse response, a stimulus signal is generated by Dirac or an external source. This stimulus signal is played in the enclosure through a sound source, and recorded through a microphone. Dirac then deconvolves the recorded response with the original stimulus to arrive at the impulse response.
Dirac will work with most Windows compatible sound devices. Dirac comes with an extensive context sensitive help system and a comprehensive manual that contain many practical hints and tips that will help you to use the tool successfully.
