WebFeb 18, 2024 · Electric and hybrid electric vehicles drastically reduce CO2 emissions, but bring many NVH (Noise, Vibration, and Harshness) challenges. Increasing comfort, quality, and reliability often prove to be more complicated with the introduction of new powertrain technologies, engine, and driveline subsystems. 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 tools that can provide results reflecting human subjective impressions. The latter tools belong to the field psychoacoustics.
