For example:
https://luxairhoods.com/Canopy-Cooker-Hoods/canopy-cooker-hood-54cm-stainless-steel
Compared to the similar Howdens Lamona option, the Lamona is 57-71db, the Luxair is 47-68db with similar power.
There is a lower powered cheaper shallow canopy Lamona version, which has an extraction rate of 321m3/h (less than half the above) and noise level of 73db, which you should probably avoid.
Unlikely to get anything more powerful or quiet than 650m3/h for a built in hood, unless you spend thousands on a Miele fan.
We went for Howdens in the end as sort of middle of the road, indigo /Dove grey cabinets in MDF.
Quite pleased really as it all seems pretty solid and OK. The Caldera thin worktop is really quite nice. Was going to source our own appliances but they made an offer on the Lamona stuff.
The only niggle is the extractor fan in the cupboard above the hob is a bit weak, the self closing doors are again a bit weak and we made the space above the hob the wrong size for a big white glass splashback.
