The coming years will be characterized by a rapidly growing market share of hybrid vehicles combining traditional IC-engine based technology with electric traction. From an acoustics point of view these vehicles are characterised by an almost infinite number of possible operational modes combining electric and conventional traction, which can result in unexpected and sometimes confusing acoustical feedbacks. Transient vibration problems are no longer restricted to starting and stopping, but are frequent events during normal traffic operation. The electric motors, power electronics and gearboxes introduce prominent high frequency tonal components. Brand sound must be re-invented to a certain extent and last but not least a totally different scenario of acoustic masking effects is putting new emphasis on conventionally “harmless” sources. These and many more topics will be at the heart of the upcoming ISNVH 2018 conference.
