Acoustic measurements constitute an essential step in order to establish the status of an acoustic environment and to develop a systematic approach toward modifying the environment and to set up criteria for improvements. Other more recently developed methodologies of acoustical measurements entail the studies of material properties and medical diagnoses. A wide variety of instrumentation exists, ranging from a simple sound pressure level meter to real-time spectral analyzers interfaced with sophisticated computer systems. Instruments may be portable for field use; and recorded field data can be later evaluated in more elaborate systems. New instruments are continually being developed---with the new advances in digital technology arriving on the scene on a daily basis, it is conceivable that more versatile and 'user-friendly' devices will become available at even lower prices.
