Experiment set ACOUSTICS 2 ADDESTATION MGA

Sound frequency generator and oscilloscope in a single piece of equipment
For most quantitative experiments in acoustics, it is necessary to have an oscilloscope and a sound generator. This is the only way that such terms as pitch, volume and tonal colour can be illustrated clearly. Sufficient quantities of a student set with both these pieces of equipment would not be feasible in terms of both cost and space. However, the MGA can fulfil both roles at once in the ACOUSTICS 2 ADDESTATION set, taking up a minimum of room and doing the job perfectly. It can provide sinusoidal oscillations at frequencies between 10 and 3000 Hz, pulse signals and even the first five harmonics for a given frequency all at once, either all at the same amplitudes or with different amplitudes.
Impressive experiments
With the MGA it is possible to find out about the most important phenomena and physical laws by experiment in a highly impressive way. For instance, it is simple to create a wide variety of sound colours and analyse them. The ideas of pitch, tone and noise can be clearly defined, graphically depicted and easily distinguished. The frequency of the supplied tuning fork can not only be determined directly but also checked by means of an experiment on beats. The speed of sound in air can be determined simply by an easily understandable measuring procedure and the Doppler effect can be demonstrated very clearly.
