as the world transitions towards new mobility platforms such as electric vehicles and hybrid vehicles component requirements are also seeing a shift in several aspects today automotive component manufacturers are focusing on producing intelligent solutions that enhance the mobility experience of todays vehicles in terms of drive ride comfort user interface entertainment and more one such important parameter of a vehicle is its noise vibration and harshness nvh levels that determines the quality of a vehicles ride 3m india rd centre electronic city bengalurufor this reason in 2017 3m india developed an indigenous acoustic insulation product called muphony that featured a fibrousliquid acoustics based multilayer insulation product and commercialised it in 2018 however muphony was primarily designed to suit diesel vehicles and in 2019 the component maker developed the integrated absorptive barrier iab that offered better nvh control in a wider variety of vehicles advt dhriti sunder bhattacharya senior general manager 3m india rd says a noise performance solution must have provisions related to noise barrier performance it must have some sort of absorption performance as well with the iab solution we are able to cater to the requirement of both diesel and petrol sectors together we are currently evaluating and tweaking the system for use in evs and hybrid vehicles as well dhriti sunder bhattacharya senior general manager 3m india rdapproach towards evs and hybrids is a little different you need to look at motor noise its tonal noise and other aspects that are different from an ice engine vehicle the calculations are completely different measurement criteria and parameters are completely different evs also come with the challenge of heat and safety and the development of thermal and acoustic materials needs to be done with that in mind bhattacharya addedoverall in terms of an ev an nvh acoustic solution needs to control road noise tyre noise electricmotor noise wind noise and ancillary system noise that is where 3m india works with their customers oems and tests new or existing vehicles with its own iab solution for optimum nvh performance at their rd centre in bengalurus electronic city an applicable noise solution needs to be effective sustainable and light weight to be commercialised ravindra jakareddy country sales manager 3m indiaravindra jakareddy country sales manager 3m india says you need to understand how the rd process evolves when developing such an acoustic performance solution we pitch ourselves as a value supplier and are price agnostic when developing a solution for a vehicle what matters is the segment in which it is getting launched what are the oems aspirations after which point we work alongside oems in offering tailor made solutions an entry level hatchback and a premium suv cannot have the same solution above all it also matters at what price bracket the oem wants to pitch the vehicle into the market our acoustic solution needs to cater to all these aspects how we differentiate our value not only depends on the products that we are selling but also on the
