Yes.
I should mention that I had no doubts of this. I already had a good friend do some thorough testing on the dB increase back in April using some actual sound meters at the appropriate distance between the old firmware and the April firmware update that increased the volume. He showed me in a video demonstration that there was roughly an 8 dB increase. He tested the old firmware at 80.5dB from the 2ft range (the distance the original Wyze tests used), and then when Wyze made the Sound update, he showed the same distance at 88.4dB from the 2ft range.
To put that in perspective, a 10dB difference is perceived as twice as loud and every increase of 10dB is equal to a 10-fold increase in sound pressure level, so this isnât quite 10 dB, so itâs not twice as loud, and it is just shy of the 90dB it was at originally at launch, but it is a significant increase from where it was (80.5dB) before Wyze increased the volume again for us.
This was one of the main things that had me excited to finally update my hub to newer firmware now that the March bugs were resolved.
I do still look forward to being able to use other chimes as they mentioned or Wyze possibly looking into a separate Siren like they talked about researching in an AMA a while ago. But I am very happy the firmware update was successful and I can have things a little louder again now.
