We’ll be continuing our studies of sound tomorrow, focusing on the components of a sound wave.
Additionally, we’ll be starting work on our own sound creations (or songs) in class.
If you’d like to get a head start, here are a couple of good online song editors (free):
- Myna from Aviary (My favorite)
- JamStudio (What We’ve Been Using in Class)
There’s also GarageBand on the Mac as well as Audacity (free) that works well on PC’s, Macs or Linux.
If you’re the enterprising sort, also check out Fission if you have a Mac.
See you (and hear you) tomorrow!

Looks like Spartanburg District 7 is on a 2 hour delay tomorrow, so we’ll be starting school at 10 am.
From Mr. Perkinson:
If we are on a two-hour delay, we will begin at 10am with a 10 min advisory. 3rd period will begin as usual and the rest of the day will be as normally scheduled.
8th graders will meet with Ms. Woodyard as previously scheduled during 3rd period or co-curriculars (Art/Band/Robotics).
Any questions?
See you tomorrow!

Like anything, sound can be used as a weapon. This is especially true because sound is a disturbance of energy. In some cases, that energy can be at such high levels that it causes pain to humans.
In this case, the US Military has been experimenting with using the LRAD (Long Range Acoustic Device) as a deterrent to potential adversaries.
It’s not pleasant to talk about weapons, etc but there is some interesting science in this segment…
