In a separate thread I asked for information about noise isolation booths and whilst continuing my research into such booths I have come across a website called Noise Help.
The website deals with various aspects of noise and includes a number of pages suggesting solutions. I have only just started looking at the site and have sent a few pages to my Kindle for bedtime reading.
The site seems to be US based but otherwise contains some really useful information (e.g. I was considering soundproof curtains and there is a good article about such curtains).
Hopefully, you will find something of use on the site.
Thank you so much for this information!
This is really helpful!
