Course content

The theoretical basis for acoustic calculations with emphasis on analytical calculations. The following will be covered in detail: simple vibrating systems, vibrations of strings, bars and thin plates, the acoustic wave equation, and solutions to this. Reflection, transmission, refraction and radiation of acoustic waves. Sound in enclosed spaces such as rooms and duct systems. Introduction to room and building acoustics. Introduction to the use of numerical methods for calculating acoustic fields.

Learning outcome

Knowledge: The candidate has (1) In-depth theoretical basis for generation, propagation, reception and damping of sound waves and mechanical vibrations. (2) Introductory knowledge about how to use general acoustic theory for common practical applications, including infrasound and ultrasound. Skills: The candidate can (1) specify and analyze mechanical systems like mass/spring combinations, vibrating strings, membranes, bars and plates. (2) know and assess simple methods for practical control of the acoustics in rooms and canal systems. (3) determine sound reflection and transmission through multi layered structures. (4) assess strategies against unwanted sound. General competence: The course gives experience in the use of theoretical/mathematical knowledge to solve practical engineering tasks.

Further on evaluation

The student has to deliver at least 4 of the 6 assignments during the semester. Each assignment consists of theoretical tasks in line with the content of the lectures. The assignments help the student train for the exam.

Report nr 1 is based on field measurements performed by the students in small groups. The measurements need to be analyzed and discussed. The individual report is delivered with calibrate sound recordings.

Report nr 2 is based on (1) the use of simulation program in Matlab on different configurations and (2) the implementation of simple numerical method. The code developed is delivered with the report.

If the course is to be repeated, all parts of the course must be taken. Compulsory activities from previous semester may be approved by the department.

If there is a re-sit examination in August, the examination form may be changed from written to oral.
