There's a reason your vacuum, car, potato chips, are way louder than they need to be. Surprisingly it’s done on purpose.

Engineers and designers manipulate the auditory element of products. Some of the biggest culprits are vacuums and cars.

Car manufacturers have been caught selling cars to fake engine sounds to boost sales.

As car tech improved, we’ve been able to product powerful noises out of them – which is what people want out of them. The louder a car is the more powerful it is perceived to be. Its not necessarily true these days. The silent sound an electric vehicle like a Tesla makes can be one example.  

The same concept can be applied to vacuum cleaners, which don’t have to be so loud. But public perception demands that they need to be loud in order to be effective. Its also got to do with making the sounds sound good. The auditory feedback they expect. Like amplifying the sound of dust particles hitting the inside of the vacuum giving you the satisfaction of knowing you’ve picked up a lot of dust.  

People may love silence, but hey love the sound of doing something right way more.

Branding can play a part in this too - Harley Davidson tried to patent the iconic sound their motorbikes make.

The sound of someone opening a Snapple bottle, is part of the associated experience customers expect, and they’ve not even drunk the juice yet. The pop is meant to symbolize freshness, but what separates it form any other bottle.

Even the humble potato chip is designed with sound in mind. Research has shown one of the most important aspects to a potato chip is its crunchiness.
