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 ...

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 ...

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 ...

Hot rods are known, among other things, for their loud exhaust systems. It would seem to the disinterested observer that the only thing at issue is how loud a car's exhaust system is, and to that ...
