Paper accepted for IOA Virtual Conference- Acoustics 2020

 

A paper submitted to the Institute of Acoustics (IOA) conference ACOUSTICS 2020  has been recently accepted for the conference proceedings. The paper is entitled “Repeatability of the balloon pop as a sound source in a room”. It has been written by Dr Luis Gomez-Agustina and LSBU MSc Acoustics student Pedro Vazquez-Barrera. The national conference will take place virtually online on 5,6, 8 and 9^th October 2020. Luis and Pedro hope to meet you online at the conference.

Professor Peter Mapp awarded IOA Engineering Medal

 

On the 16th September 2020 Professor Peter Mapp was awarded the Institute of Acoustics Engineering Medal. The ceremony took place for the first time during a Zoom meeting where IOA President Stephen Turner gave the citation for Professor Mapp. The award is specifically for contribution to acoustical engineering where the winner is normally a Chartered Engineering. Peter's contribution has been on electro-acoustics particularly public address systems, but his seminar was on Ultrasonics!

Doing acoustics COVID style

 

Professor Peter Mapp has been busy investigating the effect on speech intelligibility whilst wearing masks. Something usually only important whilst under going surgery but now... Not sure how much the Binaural Observers (Bobs) have got to say but lets how clear it is! 

Inter-Noise presentation by Dr Haydar Aygun

 

On the 25th August 2020 Dr Haydar Aygun presented his research to the Inter-Noise 2020 eCongress via Zoom. His paper entitled, "Scattering of acoustic waves in air and water filled 3D printed porous rigid materials", was pre-recorded and available to view until 6th September 2020.

PhD candidate presents her research at Inter-Noise 2020

 

On the 25th August 2020 PhD candidate Suzana Zekic presented at the first ever Virtual Inter-Noise eCongress. She presented her work entitled, "Measurement Methods of Acoustics Properties for Alternative Ventilation Ducts". Suzana did this live which was impressive as the session was very early in the morning as the conference was hosted in South Korea! Questions were through the Chair using the chat option in Zoom. A novel experience for all!

Acoustics Kit for Home Use: All Ready for 20/21

 The Acoustics Group has purchase more audio kit for home use by the incoming  2020/21 students. The additional kit consists of Behringer omni-directional measurement microphones and two channel USB 192 kHz 24 bit sound cards. This kit will be used with Windows based measurement software for calibrated data acquisition. Finally, we have identical mechanical music boxes as a simple sound devices. We hope this 'lab in a box' will give the students plenty to experiment with over the coming autumn term!  

Ultrasonic Devices & Audibility – Hearing the Inaudible Lecture

 In recent years there has been a resurgence of interest in Ultrasonic sounds & emissions, culminating in a special addition of JASA dedicated to the topic in 2018. Ultrasonic devices have a wide range of application ranging from ultrasonic tape measures and car proximity warning systems to pest deterrents and the safety surveillance monitoring of public address and sound systems used for emergency purposes. Other uses include ultrasonic cleaning and medical applications as well as antisocial behaviour deterrent devices, wind speed indicators and ‘inaudible’ ringtones. The talk will take a brief look at a number of typical applications and discuss the human sensitivity to ultrasound and the potential audibility, typical levels and issues that some of these devices and applications produce. Visiting Professor with the Institute of Acoustic London Branch will present his lecture on-line at 6pm on 16th September 2020.
