• To provide the student knowledge of different types of noise, of methods and
instrumentation for the analysis and measurement of noise and of noise prevention and
• To give the student knowledge of rules, standards, and legislation concerning noise.
• Classification and description of noise (frequency, time, space). Noise sources
(machinery, traffic, and neighbours). Standards (ISO, IEC, CEN), laws, regulations,
legislation, relevant authorities. Noise effects on humans: Loudness, noisiness,
annoyance, physiological and psychological disorders and damages.
• Sound pressure level measurement: frequency weighting (A, B, C, D, G). Leq,T, SEL,
percentile level etc. Ratings and noise descriptors. Road traffic noise, aircraft noise.
Environmental influences: distance, reflecting surfaces, background noise, and
• Sound power determination: diffuse field and free-field methods, precision
engineering and survey methods. Intensity measurement.
• Limitations of the conventional methods, binaural methods.
• Noise Abatement: Absorbers, barriers, enclosures, mufflers and lined ducts, vibration
isolation. Insertion loss, transmission loss and noise reduction. Planning and level
estimation. Hearing protecting devices. Active noise control.
Fundamentals of Acoustics, Acoustical Measurement Technique, Human Sound
Perception and Psychometry (Module 2 required, module 1 recommended).
