Hi! Thanks for this video, it's incredibly informative. I'd like to know if you worked out your TL through an average of the different wall densities (Glass, brick, timber etc)? If not, how did you get a standard TL for all the building components that presumably have different TL's?

[@socertiesDB9]

Thank you for the very informative video, kindly advise if there is a need to cacluate the NR through the wall nearest to the source of the sound only or for the all the walls of the building.

Apologies I don't look at comments normally as these resources are for my students. NR for wall is just the wall you need to look at whole room acoustic approach if you have multiple walls all with different sound issues. I'm not a published author or chartered acoustics engineer but when I come around to upgrading this resource I will ensure to add some detail on this. Thanks for your enquiry and I hope you found the result you needed.

@@silkensolutions Thanks you for your feedback, much appreciated. I managed to solve the challenge with the information from the video and a few other sources. Thanks again.

Why are you comparing Part E Building Regulations criteria of separating elements for walls and floors between habitable areas with an external façade sound insulation calculation? External façade sound insulation isn't relevant to Building Regulations Approved Document E, and would come under the jurisdiction of the local authority, with guideline internal sound levels given within BS 8233:2014. Building Regulations Approved Document E is only applicable to sound insulation between ADJOINING dwellings.

Apologies I've not got to this sooner. Yes agreed. My calculations are to show students the process and not all my data is entirely accurate. I will take note of this and if I update this resource I'll be sure to add this so there's no confusion. Thanks and I hope you enjoyed the video.
