##### Exam

The exam will take place on Tuesday, January 9, 2018 in the afternoon.

A typical exam consists of 1–2 essay tasks and 4–5 problems (5–6 in total). Correct answers/solutions are awarded 5 points. A minimum of 12 points is required for a passing grade, as well as an approved lab report. The following aids are allowed at the test: Mathematical tables, electronic calculators without text memory and our list of equations for the course (without self-written notes).

The date of the regular exam will be announced.

Tools you are allowed to use during the exam:

Your favorite dictionary, should you need one.

Mathematical tables such as such as Beta, Standard Mathematical Tables, Physics Handbook, Tefyma

Electronic calculator without a text memory or with a cleared text memory

List of useful formulae for the Electroacoustics and Ultrasonics course. (Useful Formulas for Audio Technology and Electroacoustics).

List of useful formulae for the Audio Technology and Acoustics course. (ATA – Useful formulae (VTA135)).

Note that no notes, except for corrections to errors, are allowed in any material which you bring to the exam.

Do not forget to specify all assumptions applied in your solutions to the problems, to motivate the steps undertaken, and to state the units whenever relevant!
