@Usborne lift-the-flap books are my boys favourite, so it was a treat to be asked to fact-check this book on Sound for them. And they gave me an extra copy for the library at @Cloverlea1917 📚

It's me! Come along to hear my thoughts on how spherical harmonics and intensity measurement are related to loudspeaker directivity. This is a slightly extended version of the talk I gave for @ioauk @ReproducedSound conference back in November. #acoustimaths
Our #acoustics #research #seminar at 12:00 on Wed 7th Feb comes from our own @HargreavesJon and concerns Extending the Low Frequency Acoustic Centre Concept to Directional #Loudspeakers. For more details a link to join visit

A fun evening two weeks ago 🎶 And always full to play 'hunt the room resonance' with my @Think_NS double bass 🤌🏼

@CharlieHouse8 @NIglobal Wish I could get mine working again. Got totally screwed over by @NIglobal's move to a software subscription model. Now can't use any of the hardware of theirs that we have 😔

Really exciting to be involved in this impactful project 💚
#NationalEngineeringDay 2024 celebrates engineer's role creating #sustainable future solutions. This is what we are doing with @energy_house2 at @SalfordUni, ensuring low carbon homes have acoustic credentials that match their excellent energy ones #netzero2050 #lowcarbonfuture

@duncanophone @SalfordAcoustic @SalfordUniNews @SalfordResearch Haha thanks. Hopefully the students enjoyed it enough to make it worth the £40 parking ticket I got while giving it 🙈

@MCMW_Acoustics Out of interest, is this computed in COMSOL or from an analytical model @MCMW_Acoustics? It would be interesting to see scattering from a sphere for comparison. Generally you expect more of a tail on scattered waves in 2D than 3D, but that doesn't seem to be very evident here...

@sparky_10 What was interesting was that it appears to show a sort of critical time, where all reflections are in phase, as well as a critical frequency.

A fun acoustic wave scattering visualisation engine here from @sparky_10 , & a great demo of using #PyScript 👌🏼
Check out my new FDTD animation web page Load/draw/edit images, add/alter sources, change surface absorption and more Plus play with colours, make a GIF, take a snapshot, and save a wav file #FDTD #acoustics #SoundBouncingOffStuffILike

Come work with me on building #acoustics #research! We'll be applying standard and innovative measurement techniques to gather impactful datasets and research best practice. You'll work in the field, in our world-class acoustic labs, and get to use some new toys from @Microflown.
We're #hiring! 📢 Could you work with us as a #Postdoctoral #Research #Fellow in Metrology for Building #Acoustics, and work with us on impactful research addressing noise issues in domestic dwellings? For more info or to apply visit

Great to see so many of our #Acoustics and #Audio students graduating yesterday, and lovely to be able to stick about and celebrate afterwards 🍻
Congratulations to the 50 odd students who graduated from our #Acoustics and #Audio courses yesterday. Here's a few we got snaps of. Around 32 undergraduates, 16 postgraduate taught, 3 MSc by Research and 1 PhD. Go forth and make the world sound better! 🎉🎓 #graduation2023
