It's an iphone app called decibel and yes it is a freebie.
Measured 120 db at the Raven's NFL game yesterday. Yikes!
Heard it live….and now at home
Went to King Crimson concert 9/11/21 at the Anthem in DC. Pretty sweet seats balcony just left of center towards rear. Measured SPLs in the 90s on my smartphone db meter app.
Now the CD of the concert was issued and got my copy yesterday. Listening to it today.
Gotta say the home experience on my big Ohm F5s is fairly close to live. Isn’t that what it’s all about?
Very fortunate occurrence for an “audiophile” to be able to make such a comparison between a live event like that and how it sounds at home. First time ever for me. Fun fun fun! Had to bring it up here in hopes that someone might care. 😊
