Evidence layer

Claim by claim

The source study was found, but the study's evidence could not be profiled, so these claims couldn't be checked.

Claim 1 of 5Not checkedScientists have developed a device that can dramatically reduce sound reflections by effectively 'swallowing' sound, and it can be 3D-printed and inserted directly into an existing pipe.View evidenceHide evidence

As stateddramatically reduce

Not checked

The source study was found, but this claim couldn't be checked against it.

Claim 2 of 5Not checkedThe new design is a 'sonic black hole' that differs from conventional versions because it is manufactured independently of the duct and then inserted into it.View evidenceHide evidence

Not checked

The source study was found, but this claim couldn't be checked against it.

Claim 3 of 5Not checkedThe prototype tested by the researchers was a 15-centimeter-long, 3D-printed structure with 29 rings mounted on a central rod, inserted into an impedance tube and measured with speakers and microphones.View evidenceHide evidence

Not checked

The source study was found, but this claim couldn't be checked against it.

Claim 4 of 5Not checkedThe article says the reflected sound broadly matched computer simulations, but the device did not completely eliminate echoes.View evidenceHide evidence

As stateddidn't completely eliminate echoes

Not checked

The source study was found, but this claim couldn't be checked against it.

Claim 5 of 5Not checkedThe simulations suggested the plug-in design reflects less sound than a conventional sonic black hole across a broader range of frequencies, which the article attributes to resonances in the cavities occurring at higher frequencies.View evidenceHide evidence

As statedconsiderably wider

Not checked

The source study was found, but this claim couldn't be checked against it.
