If you’ve been following the Frequency Fundamentals series, hopefully you’ve already had a go at the first two quizzes (1, 2), designed to test your knowledge of frequencies and harmonics. If not – now’s the time!

This new quiz is a recap of the course, for students who feel they’ve really got to grips with the material.

As usual, the quiz consists of 10 questions, chosen randomly each time you take it so you can keep practising as you learn. This one covers material from throughout the Frequency Fundamentals series, and digs into some corners of the course which the first two quizzes missed out.

You might want to refresh your memory before you dive in:

1. What’s ‘Frequency Training’ All About?
2. Introduction to Frequency Training
3. Percussion Frequencies Part 1 – Drums
4. Percussion Frequencies Part 2 – Cymbals
5. Frequency Band Characteristics – Part 1
6. Frequency Band Characteristics – Part 2
7. Background: EQ Feathering and Spectrum Analyzers
8. Harmonics and Distortion

And the first two quizzes:

Quiz 1: Percussion Frequencies

Quiz 2: Frequency Bands and Harmonics

Also, if you’re just joining the “Hearing Effects” course, now’s a great time to make sure you’re up to speed on frequencies – if you can ace this quiz, you’ll probably manage fine!

We’re always keen to hear from you – let us know what you think of the new quiz in the comments below!

Following on from the previous quiz on Percussion Frequencies, we’re opening up a new quiz today: covering Frequency Bands and Harmonics.

Once you’ve got to grips with the starting material in the Frequency Fundamentals course, you should find you’re getting a good sense of where different frequencies lie in your hearing range. The second half of the course then introduces the 10 standard bands of frequencies used when analysing audio and making adjustments to the frequency balance:

Now comes the time that we need to address actual characteristics of different frequencies, as well as the different octaves that humans can hear. (As in, how many are there actually?)

As always, let’s follow the flow of logic. The simple question first:

How many octaves are there in the human hearing range of 20-20kHz?

The answer is 10.

If we take the lowest frequency humans can hear, which by now you know is 20Hz, and then simply double that number until we reach the 20k range, we’ll end up with 10 total octaves encompassing the 20-20kHz range.

Here is the exact break down: Click to read the rest…
