1-2 Fundamentals of room acoustics  

Seminar and tutorial

Field assignment: measure RT in two chosen rooms using Schröder’s reverse integration

3 Spatial hearing 

ILD, ITD, HRTF 

Lab – find your personal difference limen for direction 

4 Room acoustics simulation

        Conventional reverb – direct + early reflections + diffuse tail

Raytracing vs waveguide simulations 

Lab session in COMSOL

5 Spatial audio reproduction – simulation of ’soundscapes’

Binaural, cinematic 

Ambisonics, VBAP, wavefield synthesis 

6 Virtual acoustics in VR-environments and telepresence

         Guest lecturers from industry (Ericsson, ACAD)

7 Field trips to Stockholms Konserthus (active acoustics), KTH SCI MWL (anechoic room and more),  KMH Lilla Salen, 28-channel speaker dome and dummy-head microphones

8 Presentations of individual project outcomes

Be able to

• describe the fundamentals of statistical and geometrical room acoustics
• make basic calculations of room acoustic parameters for rectangular rooms
• describe the principles of directional hearing and how they relate to acoustics indoors
• make informed use of head-related impulse responses and transfer functions
• simulate simple scenarios with a few sound sources in virtual rooms that have given properties
• describe the characteristics of modern spatial audio techniques, including binaural, VBAP, Ambisonics, Dolby Atmos and wave-field synthesis

Basic classic physics, especially wave theory as in SK1120; fundamentals of acoustics e.g. DT1175; basic signal processing including at least digital audio and filtering.

The first two are for in-depth studies with reading guides, the last two are minimum requirements that should be learned in their entirety.

Mathworks Matlab+COMSOL for programming assignments

Students at KTH with a permanent disability can get support during studies from Funka:

Funka - compensatory support for students with disabilities

P, F

• EXA1 - Examination, 7.5 credits, Grading scale: P, F

Based on recommendation from KTH’s coordinator for disabilities, the examiner will decide how to adapt an examination for students with documented disability.

The examiner may apply another examination format when re-examining individual students.

Active participation in all seminars, preferably on location, remote participation will be possible. 

Reading assignments and an individual project work. Performing simulations of sounds in rooms during the labs. 

Written personal reflections after each session.

To pass the course the student must

• attend all sessions; if not possible, discuss with the examiner what to do instead
• make at least one summarizing presentation to the class about a given section from the course textbooks
• write a short but non-trivial personal reflection on each session in time for the next session
• comment in writing on the reflections of other students in time for the session after that
• For FDT3318: do all labs and submit a lab report for each, and present and summarize a research article of one's own choice.
  For SD2101 and DT2217: conduct a project in groups of two students, write a short report, and present the project at the final session.
  Master students are encouraged to do also the labs, but for them it is the project that counts.

If the student is unable to attend one or more sessions, or to do one or more of the given assignments, to discuss and agree on alternative assignments with the examiner.

• All members of a group are responsible for the group's work.
• In any assessment, every student shall honestly disclose any help received and sources used.
• In an oral assessment, every student shall be able to present and answer questions about the entire assignment and solution.

"Any help received" includes machine help, which must also be disclosed.

This is the first time that this course is offered, and changes are likely for the next course offering.
