Introduction,rom a signal that changes over time and corresponds to an unrepeatable phenomenon. In the following sections, several parameters that describe the global behavior of sound, such as the equivalent level, the frequency weighted levels, the exceedance levels and the spectrum, are discussed. The stabilization time of all of them is also analyzed.

Transducers,ge. In this chapter its main characteristics and applications to different sound fields are studied, in particular its frequency response and directional pattern. Omnidirectional speakers and audiometric earphones are also studied, since thety are important in architectural acoustics and psychoacoustics.

Basic Algorithms for Acoustical Measurements,re with native handling of vectors, matrices, and arrays, in which vector and matrix operations with real and complex numbers are invoked as if they were simple numbers. Besides simple sound file management, we will consider equivalent levels, calibration, time weighting and energy envelope, frequency weighting  and statistical analysis
