The 2011 Nissan Leaf was the first electric car equipped with Nissan's Vehicle Sound for Pedestrians called 'Canto'.. Electric vehicle warning sounds are sounds designed to alert pedestrians to the presence of electric drive vehicles such as hybrid electric vehicles (HEVs), plug-in hybrid electric vehicles (PHEVs), and battery electric vehicles (BEVs) travelling at low speeds.
The torsional deflection of a simple cylinder cannot radiate efficiently acoustic noise, but with particular boundary conditions the stator can radiate acoustic noise under torque ripple excitation. [8] Structure-borne noise can also be generated by torque ripple when rotor shaft line vibrations propagate to the frame [9] and shaft line.
Fit some big ass speakers to the underside of the car, use specially-shaped air channels to help project said noise, and crank up the power until hitting the 126-decibel mark the outgoing Hellcat ...
Noise, vibration, and harshness (NVH), also known as noise and vibration (N&V), is the study and modification of the noise and vibration characteristics of vehicles, particularly cars and trucks. While noise and vibration can be readily measured, harshness is a subjective quality, and is measured either via jury evaluations, or with analytical ...
Mercedes calls the sound "G-ROAR," because that is just what German car brands do. The Mercedes G-Wagen EV Makes Unique Sounds 'Inspired' by ICE Cars Skip to main content
Sound levels of such horns are approximately 109–112 decibels, and they typically draw 2.5–5 amperes of current. Again, these horns can be either single, or arranged in pairs; typical frequencies for a pair are 420–440 Hz and 340–370 Hz (approximately G ♯ 4 –A 4 and F 4 –F ♯ 4) for this design.

There was a “'loud whining noise,' that diminished and then increased followed shortly thereafter by smoke emanating from the area of the accident site," stated a witness, according to the report.
Car alarm unintentionally triggered by the acceleration sound of a Porsche GT3 RS. Although car alarms of some kind have been available since the beginning of the automobile era, the dramatic increase in their installation in the 1980s and 1990s coupled with the fact that nearly all types of car alarms are easily triggered accidentally ...
