Three of the best 2017-18 IOA Diploma projects undertaken by students at the London South Bank University will be presented. Please read the abstracts below.  

 

1-This report reviews and compares gathered data and perception on acoustics, ventilation and overheating in residential dwellings. A review of residential buildings exposed to the same noise sources has been undertaken. The dwellings and the external environment have been monitored to obtain internal and external noise levels. Additionally, internal temperature and humidity levels were monitored. The information collated was compared to current guidance, legislation and the draft ANC Acoustic, Ventilation and Overheating Residential Design Guide. Understanding of resident’s perception on acoustics, ventilation and overheating elements of their property was obtained and compared against the data collated.

2-Traditional sound sources, such as pistols, balloons or clappers, which seek to create Dirac-like impulses, are still commonly used in the industry despite their reported weaknesses. This is mostly due to their cost-effectiveness and convenience. This study provides a thorough review of impulse sound sources in usage as well as undertaking a practical investigation into the use of balloons and clappers as suitable impulse sound sources.

3- This project investigated the accuracy of a speech privacy auralisation used by an acoustic consultancy.  The baseline acoustic performance of their meeting rooms was tested, giving speech privacy ratings of good and basic. The sound insulation results were used to create auralised versions of the same scenarios and these were compared to the real-world performances. A method was applied to correct for identified inherent weaknesses and improve accuracy.
