Innovation: Sound solution
Your support helps us to tell the story
From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it's investigating the financials of Elon Musk's pro-Trump PAC or producing our latest documentary, 'The A Word', which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging.
At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story.
The Independent is trusted by Americans across the entire political spectrum. And unlike many other quality news outlets, we choose not to lock Americans out of our reporting and analysis with paywalls. We believe quality journalism should be available to everyone, paid for by those who can afford it.
Your support makes all the difference.ORDINARY noise-proofing with porous or fibrous materials may protect your ears, but it has been criticised as a fire hazard, a haven for bacterial growth and as being difficult to dispose of. Scientists at the Fraunhofer Institute for Building Physics in Stuttgart, Germany, have now developed a sound-absorbing membrane 0.075mm thick that can be made of plastic or stainless steel. It has the additional advantage of being able to protect against low-frequency sound that is not absorbed by conventional proofing.
