Tiger Lake, but it looks more like Asus
proprietary tech. To test it, we played the
sound of Ghostbuster’s Ecto1 siren on a

dgfl), which features Bang & Olufsen audio

and its own noise-cancellation technology.

On the HP, we could still hear the reduced,

but distinctive sound of the siren along with

works quite well.
