Story of Why this story? The channel's weekly summary: what went up this week, what is drawing views now, and where the channel stands among similar channels.
This can SEE Sound!
An electric screwdriver gives Marques Brownlee's new camera something to look at, or rather, listen for. Pointed at the tool, the acoustic imager marks where its noise is coming from on screen. Brownlee's verdict is pleasingly direct: "And it absolutely works."
"This can SEE Sound!" has reached roughly 1.8 million views, making it his most-watched new upload of the week and the channel's busiest video right now. It is a compact gadget investigation with a wonderfully specific snag: the rubber port flap promises HDMI, but Brownlee opens it and finds no HDMI socket.
Before that, he shows how an array of 64 microphones locates sound, tries a high-frequency tone from his phone and takes the device outside to test it on an electric vehicle. Pulling the trigger saves a decidedly modest-resolution photo. The sound-finding is the attraction, not the photography.
Viewers are already supplying a job list. Some describe using acoustic cameras to find industrial air leaks, including in a brewery and fiberglass manufacturing. Others have smaller targets in mind: the mosquito that refuses to reveal itself at bedtime.
The week's other arrival, "Macbook PROLED XDR Impressions: They Said They Wouldn't!", turns to the first touchscreen Mac. Meanwhile, his iPhone Duo review remains a substantial source of daily viewing, with the Homeview impressions also drawing attention.
Across the channel, daily views are a little below their usual level, and subscribers were unchanged over the week. Among nearby tech channels, Unbox Therapy is experiencing a stronger-than-usual daily flow, while Linus Tech Tips is modestly above its norm. Brownlee's week has its own useful contrast: Apple's changing screens beside a camera that makes noise visible.

I’ve played around with a $20000 version of this for detecting air leaks on pipes in a brewery, it has a physically wider array of microphones and was amazing how far away it could detect a hissing air leak
@maldzySee it on YouTubeI've used one of those to detect air leaks on a vacuum bag for fiberglass manufacturing
@pedroshonSee it on YouTubeMy parents have this built in for when I walk around the house at night.
@Jira9See it on YouTubeVery useful for finding noise in a car and where it’s coming from 👍
