The Helmholtz resonating frequency is actually one of three different forms of charge filling associated with intake design. Remember we said the intake design was much more than simple airflow? These ...

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 ...

A tuned intake induction system using a Helmholtz resonator was applied to an in-line six cylinder, four cycle heavy duty diesel engine. The system adopted was designed to maximize the engine ...

Engines can develop some unpleasant noises under certain conditions, thanks to fiendishly complicated harmonics in the intake-air tract, and so clever engineers often use the principles of Helmholz ...

A cavity-type RESONATOR so constructed that it will vibrate only at a particular FREQUENCY, giving off little energy to the outer medium, and therefore resonating for a considerable length of time. It ...

A listening room, defined by its dimensions, can be mapped in terms of a series of pressure peaks and nulls, in all three dimensions. This refers to the creation of standing waves (modes), and the ...

Hand clapping is ubiquitous behavior for humans across time and cultures, serving many different purposes: to signify approval with applause, for instance, or to keep time to music. Acousticians often ...

The 2023 Chevrolet Corvette Z06 is powered by a naturally aspirated 5.5-liter V-8 making 670 hp and 460 lb-ft of torque, making it the world's most powerful V-8 without forced induction, found in a ...
