The FIA has revealed details of a sound generator which is in the pipeline to crank up the noise produced by F1s hybrid engines. F1s stakeholders recently signed off a package of engine regulations for 2017 and beyond, with moves to improve the sound of the cars part of the agreement.Fans and some leading figures within the sport, including Bernie Ecclestone, have argued that some of F1s traditional appeal has been diluted since the advent of quieter turbo engines in 2014. Speaking at the Spanish GP, Fabrice Lom, the FIAs head of powertrain, said: There is a perception that the sound is not enough, and we have had very good results with what we call a sound generator.It is not fake, but it is not purely natural, lets say, but that would really increase the intensity and quality of the engine sound. Mercedes have taken a lead in looking at ways to increase the sound of the current engines and recently advertised for a noise engineer to join their Brixworth engine base with the remit of improving the turbo hybrid V6 noise appeal without sacrificing power unit or vehicle performance.Lom, a former engineer at Renault, says plans for the sound generator are still in the early stages.Its a bit early to say [how it will work], its really under development, he said.When is the Spanish GP on Sky?But we are using the energy on the exhaust, even if it is not very high, because we recover a lot [of wasted energy], to increase it.The FIA, F1s governing body, is aiming to have some device in place by 2018 at the latest.Watch the Spanish GP live on Sky Sports F1.
