Objectives

The major in Acoustics and Audio Technology gives fundamental knowledge about acoustical phenomena, human hearing and audio technologies, and also facilitates the students to apply the knowledge in practice.

The fields of electroacoustics, room and building acoustics, noise, musical acoustics, and audio signal processing are focused in the studies. A central field in the studies is technical psychoacoustics studying human hearing mechanisms, which is a cornerstone in the development of acoustical and audio technologies for human listeners. The fields together constitute the field of communication acoustics, where there exists always a human listener at the end of the acoustic communication channel. Digital signal processing is currently an important tool in acoustics and audio engineering, and the teaching also emphasizes the understanding of its general principles and of fundamental audio processing algorithms.

The target of the major is that the students could use their learning outcome flexibly in different tasks in industry and in academia. For example, the student should know why and how modern lossy audio codecs (mp3, AAC) work, or he/she should be able to measure, understand the perceptual aspects, and design the acoustics of a class room or a noise barrier. Some exemplar fields where the students are foreseen to be competent are sound recording and reproduction, audio coding, music technology, acoustic measurements, active noise cancellation, audio signal processing, room and building acoustics, and environmental noise. If the student wants to work as a certified acoustics consultant in Finland, at least 10 cr on building technology is required.

The research conducted in Aalto University in the fields of this major has focused on following topics: spatial sound reproduction, concert hall acoustics, synthesis of musical instruments and natural sounds, loudspeaker and headphone reproduction, spatial sound psychoacoustics, digital filtering of audio signals, and modeling of room acoustics. The University is facilitated with top-level acoustical laboratories: three anechoic chambers, a standardized multichannel listening room, sound-proof listening booths, and immersive audiovisual environments.

Content and structure

The major can be completed either as a long (55-65 cr) major or a compact (40-45 cr) major. Students taking the compact major take also a master level minor (20-25 cr). Students taking the long major may include an optional minor in their elective studies.

The major consists of 30 cr of compulsory courses and 10-35 cr of optional courses depending on the choice between long and compact major.

All the major courses are intended to be studied during the first year of master’s studies. The course ELEC-E5600 Communication Acoustics is a recommended prerequisite to the other major courses.
