The Ear
Psychoacoustics
100

It is the brain's perception of stimulus caused by a variation in air pressure.

What is Sound?

100

It refers to the perceived highness or lowness of a sound, which is primarily determined by the frequency of the sound wave.

What is Pitch?

100

Digital signals that are bound to rules regarding size, shape, and how fast they can change.

What is Digital Audio?

100

This organ is responsible for the sense of hearing in humans and many other animals. It plays a crucial role in perceiving and processing sound.

What is the ear?

100

This effect is the ability to focus on a single speaker amongst a crowd.

What is the cocktail party effect?

200

It is a graphical representation of how a signal, such as sound or electrical voltage, varies with time. It shows how the amplitude of the signal changes over a specific period.

What is waveform?

200

It is a term used in music to describe the unique quality or character of a sound that distinguishes it from other sounds.

What is Timbre?

200

It refers to the number of samples or measurements taken from an analog signal within a specified time interval.

What is sample rate?

200

These are the three bones located within the ear that help process external vibrations into perceivable sound.

What are hammer, anvil, stirrup?

200

The audio illusion that sound is coming from the centre when it is actually not.

What is a phantom centre?

300

It refers to the number of oscillations or cycles of a sound wave that occur in one second.

What is Frequency?

300

It has additional frequencies which are integer multiples of the fundamental frequency, and are sometimes called overtones.

What are Harmonics?

300

It is widely used as a communication protocol and file format in the world of music and sound production and helps create digital data that represents a sound.

What is MIDI?

300

Taking information from one medium to another medium. Sound waves turned into electrical physical pulses.

What is Auditory Transduction?

300

This concept is the difference in sound intensity between the ears. It is one of the cues used to determine the direction/location of a sound source, and represented by the PAN function in a DAW.

What is inter aural amplitude difference?    

400

They provide a convenient and standardized way to describe the intensity and loudness of sound for human perception.

What are Decibels?

400

It allows you to selectively boost or cut specific frequency ranges, altering the tonal balance of a sound.

What is EQ?

400

A controlled form of noise added to a digital signal during the process of quantization.

What is Dither?

400

The decline of hearing loss as you age.

What is Presbycusis?

400

This concept helps the brain determine the direction of a sound source in three-dimensional space. It is often represented by the delay plug-in.

What is inter aural time difference?

500

If this effect occurs, it can have a positive or negative effect as two waveforms are interacting with each other.

What is phasing?

500

This process breaks down any sound into sine waves, and allows for a detailed examination of its harmonics.

What is Fourier Analysis?

500

This theorem describes the conditions under which an analog signal can be accurately reconstructed with no loss of information, as long as it is sampled at a frequency greater than or equal to twice per cycle.


What is Nyquist Theorem

500

This chart indicates how loud in dB SPL (Sound Pressure Level) a sound at one frequency must be in order to be perceived as equally loud as a sound at another frequency.

What is Fletcher/ Munson chart?

500

It is a function that describes how the human ears modify the sound waves from a sound source before they reach the eardrums. Ex. Removing the high frequencies from a sound will make it sound quieter.

What is head related transfer function?
