If exhaust sound quality matters to you, there’s more to it than how annoying it is. Hot rods are known, among other things, for their loud exhaust systems. It would seem to the disinterested observer ...

Resonators and mufflers are both parts of a vehicle's exhaust system. But if you look at the two components side by side, you may struggle to see the difference between them. That's not to say that ...

In either the 1850s or 1860s, German physicist Hermann von Helmholz created a device to analyze sound. In 2005, that same sort of device made its way into the airbox of the new 3.8-liter flat-six of ...

SAE Transactions, Vol. 103, Section 3: JOURNAL OF ENGINES (1994), pp. 970-979 (10 pages) Helmholtz resonators are widely used for the noise reduction in vehicle induction and exhaust systems. This ...

A round of applause, please: Scientists have finally figured out what’s behind the sound of clapping. The research pinpoints a mechanism called a Helmholtz resonator — the same acoustic concept that ...

We get it: You want your car to turn heads. But to do that, it's not enough to make your car look good. You want it to sound good too. That sound all comes down to your car's exhaust system — at least ...

This is a preview. Log in through your library . Abstract Helmholtz resonators are widely used for noise reduction in vehicle induction and exhaust systems. This study investigates the effect of ...

Researchers describe an acoustic meta-surface that uses pingpong balls, with small holes punctured in each, as Helmholtz resonators to create inexpensive but effective low-frequency sound insulation.
