Objectives
This course provides a practical understanding of how sounds behave in air and how they are perceived in real spaces. A series of audio demonstrations and hands-on MATLAB examples are provided to allow participants to have an in-depth understanding of these important topics. In addition, there are several MATLAB based calculation facilities that will be built by the participants during this course. These facilities include:

  • Compute the sound pressure, sound intensity and sound power
  • Adding correlated and uncorrelated sound in dB
  • Converting between frequency and bark scale
  • Compute the room acoustics parameters, such as standing modes, standing wave, reverberation ratio.
  • Compute direct and reverberation sound intensities
  • Compute virtual pitch and other psychoacoustics parameters
  • Compute the linear and nonlinear parameters in propagation in air

There are several interesting phenomenon and commonly asked questions in acoustics and psychoacoustics that will be covered in this course:

  • How sound propagates in air, water, and solid?
  • How sound reflection can be exploited for applications?
  • How constructive and destructive sound interference can be applied in practical applications?
  • How can we focus sound as directional beam, behaving like a sound beam?
  • How sound can be bend (diffraction and refraction)?
  • How sensitive is our human hearing?
  • Can we really need to hear sound beyond 20 kHz?
  • Why current hi-fidelity audio is sampling at 96 kHz and beyond?
  • How we can synthesize audio effects, like reverberation, chorus, and special effects?
  • Can opera singer break a wine glass?
  • How do we measure sound pressure level? And how does it relate to human hearing level?

Prerequisites:
There is no pre-requisite in taking this course as all the fundamentals on acoustics and psychoacoustics will be covered. This course can also be extended into a full-fledge undergraduate course lasting a single semester.

Duration:
2 Full Days
