DATA

Psychoacoustics is our umbrella term:

This image shows how sound can reflect off surfaces and make its way back to the microphone.

This image is another way to show how sound can reflect of a surface and make its way to the listener at a different time and angle.

These two images are from a video in the pre class and they describe how we can't hear different sounds if they are less then 20 milliseconds apart.

These two images show a visual representation of destructive interference using two of the same images slightly offset.

timbre, also called timber, quality of auditory sensations produced by the tone of a sound wave. The timbre of a sound depends on its wave form, which varies with the number of overtones, or harmonics, that are present, their frequencies, and their relative intensities (Hosch, 2006). Link.

Timbre is the fundamental frequency and the resonant frequencies. 2 identical frequencies in phase will increase by 6dB. A3 is 440hz. ADSR Attack decay sustain release.

synthesiser use sine waves to create sounds.

sawtooth wave is bright and brassy character. contains both even and odd harmonics.

square wave is made of only odd harmonics.

Triangle wave is made of only odd harmonics.

Books to look into:

understanding and crafting the mix, the art of the recording book.

queit places can be almost as bad as loud places.

Reflection

What?

What activities have I completed this week?

I watched the pre class videos on destructive interference and sound reflections.

So What?

So, what have I learned this week?

We also learned about what happens when you combine different waves.

Am I on the right track with this unit?

I think so.

Now What?

Now what will I do to move forward?

I need to work on my learning journal.

What feedback did I receive this week?

Add notes below from any feedback provided in class, during activities or as part of tasks.

My learning jurnal is lacking.
