The Human Ear
Sound Character
100

We measure the intensity of a sound in Decibels, but when referring to sound as humans hear it, this type of Decibel measurement is used.

What is dB SPL (Sound Pressure Level)?

100

These two guys determined that humans are most sensitive to 1k-4k and discovered the human frequency response.

Who are Fletcher and Munson?

100
This process is used to boost or cut frequencies on an audio signal.

What is equalization?

200

It's the height of the soundwave - we use this measurement to determine the intensity.

What is amplitude?

200

Our ear - much like a microphone - acts as this type of mechanism.

What is a transducer?

200

This frequency group is often described as "nasal" and covers a wide series of frequencies.

What are mids?

300

The amount of times a soundwave occurs over a second of time is called this.

What is frequency?

300

While we don't have a flat frequency response as humans, we hear all frequency ranges most evenly at this level.

What is 80-85 dB?

300

The Nyquist Theorum states that in order for digital conversion to happen, the sample rate must be this many times the highest sampled frequency.

What is twice/2x as high?

400

Sound waves have areas of compression and rarefaction, making them these types of waves.

What are longitudinal waves?

400

After the direct sound, we hear this type of signal delivery next!

What are early reflections?

400

In digital audio, bit-depth determines these two factors for a signal.

What are dynamic range and signal-to-noise ratio?
