Course Objective

Noise pollution represents one of the most common sources of discomfort within society. However, it is also one of the least prioritised forms of environmental pollution, particularly in our country. This inconsistency can be attributed to the fact that the impact of noise on individuals or society is not readily identifiable, as it manifests as a consequence of long-term accumulation and/or presents indirect indications.
The ongoing rise in noise levels in urban areas has led to the expansion of noise control activities across a multitude range of scales, from the urban level to the building and even the element level. The lack of efficacy at the urban scale increases the importance of noise control strategies at the building envelope level, in addition to those at the spatial scale, in order to create comfortable spaces in terms of noise.
In particular, the recently updated noise legislation in our country makes the consideration of noise as a design parameter a mandatory element for spaces to have the desired acoustic quality.
In this context, the objective of the course is to enhance auditory awareness by emphasising the significance of the concepts of sound and noise, noise control and silence design, and to provide students with information about solutions/suggestions for noise control in buildings within the scope of relevant regulations and standards.

Learning Outcomes of the Course Unit

1   to get the basic information on noise pollution and effecs on the health
2   to examine the basic information about noise control according to user comfort, building design and noise control standards and regulations.
3   to use basic principles and methods on noise control in order to provide acoustical comfort conditions in buildings depending on the function
4   to identify the effects of architectural design and material selection on aural comfort conditions of buildings
5   to make general design decisions based on the legal regulations and acoustical calculations on architectural applications
