Further details for each course are listed on this page. To register your interest in any of these training courses please follow the link to ‘Register Your Interest’, supply a few basic details and one of our course administrators will get in touch with you directly.

Designing for Speech Intelligibility

Learn the factors that affect and limit the speech intelligibility in a space and how they can be overcome and controlled.

You will learn...

  • Relevant British and European intelligibility standards
  • Intelligibility metrics
  • Factors that affect the Speech Transmission Index
  • Loudspeaker choice and placement
  • Reverberation times
  • Direct-to-reverberant ratios
  • Signal-to-noise ratios, static and time variant
  • Intelligibility limits in an acoustic space
  • Measuring the Speech Transmission Index (STI-PA and indirect methods)

Who Should Attend?

Everyone involved in specifying, designing or installing sound systems or voice alarm systems where speech intelligibility is important, including engineers, installers, system designers, estimators, consultants and local authorities.

Loudspeaker, Room Acoustics & How They Interact

Learn how the correct selection and placement of loudspeakers in a given acoustic environment, has a direct relationship on perceived sound quality in the listener’s seat.

You Will Learn...

  • The acoustic signal path from the loudspeaker to the listeners ear and what it does to the audio signal
  • Direct to reverberant ratio and its relevance to speech intelligibility and music fidelity
  • How to optimise the direct to reverberant ratio for improved system performance
  • The key characteristics that define a loudspeaker: sensitivity, power handling, maximum SPL, bass extension, fidelity and dispersion
  • How we define dispersion, a look at polar plots and isobar plots, what they tell you about the acoustic performance of a loudspeaker and how they enable you to compare different devices
  • How an informed choice of loudspeaker enables you to optimise the direct to reverberant ratio and therefore maximise audio quality

Who Should Attend?

Everyone involved in specifying, designing, installing or using sound systems – including contractors, estimators, system designers, live sound engineers and theatre technicians.

Making Waves – Acoustics for Sound Engineers

Learn how to have a better understanding of what happens to sound after it leaves the loudspeakers.

You Will Learn...

  • What sound is and how sound travels
  • Relationship between the speed of sound, wavelength and frequency
  • Amplitude
  • How the decibel works
  • Equal loudness contours and the implications of
  • Frequency weighting
  • Point, line and plane sources and their propagation
  • Air absorption, reverberation and absorption
  • Diffraction, interference, temperature and the speed of sound
  • Refraction
  • The Doppler effect

Who Should Attend?

If you work in the sound and communications industries and need to have better understanding of what happens to sound after it leaves loudspeakers, this is a course you will benefit attending.
