Featuring what is possibly the craziest beat using goal post sounds you’ve ever heard.
Elias Pettersson has touched a lot of posts this season.
According to the NHL, Pettersson has hit a total of eight posts and crossbars this season, leading the league. This does not count the posts he hit that came out first from the goalkeeper, as these count as saves, and that of course does not include shots that came out of the post and scored. a goal.
A goal post makes a musical sound when a puck hits it – a distinct “ping” that fills a goalie with joy or dread. It’s a sound unlike any other in sports.
But what musical sound does it actually produce? What is the height or frequency of a goal post?
Pitch is the quality of a sound caused by the rate – or frequency – of the vibrations causing the sound. Sound with a high vibration rate causes a higher pitched sound, while sound with a low vibration rate causes a lower sound.
In Western music, certain frequencies have been given names in a 12 semitone scale from A to G #. While there are all kinds of micro-tones between every musical note in this range, these are the musical notes that Western listeners would be used to hearing in everything from classical music to modern pop.
So what musical note is played when Pettersson is pinging a message?
This is Sportsnet’s “Pettersson post pack”, containing all of Pettersson’s pings from this season.
If you listen closely you may notice that they all seem to play at about the same pitch, although some sound a little duller, perhaps because the puck didn’t hit the post squarely or has just grazed the post instead of making a solid impact.
I took the audio in Logic Pro to get a better read of the frequencies of each of these mailing results. All of Pettersson’s ping messages all seem to ring at around 3000Hz, which is very close to a high F #, aka. Go.
On some later tubes, however, there also appears to be a tone at around 1000 Hz, which falls between a B and a C. Sometimes we get a frequency around 1420, which falls right between an F or F #, but an octave lower than what we normally get. It still has the harmonic at around 3000Hz, so there is some consistency.
It’s not just Pettersson’s messages. If you listen to Adam Gaudette’s goal against the Montreal Canadiens on Monday, the post he hits rings at the same F # frequency as Pettersson’s shots.
This makes sense, of course. The shape and resonance of the goal post does not change, so no matter what hits it – it will vibrate at the same frequency and create the same tone.
What’s really interesting is that the goalposts were ringing at a lower frequency.
Cody Hodgson’s bardown goal in “Game 8” against the Boston Bruins in 2012 sets a tone very different from Pettersson’s posts this season. It hits the bar and resonates at around 2220Hz, which is almost exactly C #, but more than an octave lower than Pettersson’s F # posts. It’s a much lower tone.
If you listen other items from the same season, they sound a lot like Hodgson’s, a much lower frequency than this current season’s posts.
This means that at some point in the past decade something changed in the NHL goalposts causing them to vibrate at a higher frequency, producing a higher pitched “ping” sound.
Maybe it was in 2013, when not only did the NHL cut net, changed the top corners of the goal posts. Where they were previously more rounded, the new corners were much more square. Does this change explain the change in height?
Whatever the cause, modern NHL goalposts make a higher pitched sound when hit by a puck. Do what you want with it.
What I did with it was a sick beat.
