However, the trend with modern homes (houses and flats) to create open plan layouts with combined kitchen and living spaces makes appliance noise feel more intrusive.
I live in a modern (new build) flat with a combined kitchen and living room which I have come to dislike.
The constant hum of the fridge/freezer - harmless 'white noise' to some - is annoying when it's ever present in the living room. My food processor sounds like a drill penetrating concrete.
The worst offender is the cooker hood or cooker extractor. It sounds like a jet engine about to take off. It's impossible to listen to music or other audio (even with headphones) while the cooker hood is switched on.
Washing machines have improved a bit on the noise front, but many UK homes still have washing machines in the kitchen - problematic if you have an open plan layout. Modern front-loading washing machines also have ridiculously long wash times for normal wash programmes e.g. 3 hours. Imagine having to listen to your washing machine for that duration while sitting in your living room.
All these things have made me really dislike the open plan layouts that are the default in new build housing today.
