Audio terminology pdf

What are terminologies of sound?

Sound level - The intensity of sound measured with a sound level meter and one of its weighting networks. Sound level meter - A pressure-sensitive device which measures loudness. Sound power - The total sound energy radiated by a source per unit of time. Sound pressure - A dynamic variation in atmospheric pressure.

What is PA system terminology?

(Public Address system) A sound amplification system comprising a microphone, amplifier and speakers.

What are the 5 elements of sound?

They are the frequency, amplitude, wave form and duration, or in musical terms, pitch, dynamic, timbre (tone color), and duration. The frequency, or pitch, is the element of sound that we are best able to distinguish.

What are the types of terminologies?

Terminological theories include general theory of terminology, socioterminology, communicative theory of terminology, sociocognitive terminology, and frame-based terminology.

What are the 6 sources of sound?

Few natural sound causes are humans, flowing water, wind, flowing streams, animals, avalanches, and many more. Sources of artificial sounds are factories, fans, automobiles, airplanes, helicopters, trains, explosions, home appliances such as vacuum cleaners.

What are the three levels of audio?

An Overview of Audio Levels

There are three main Audio Levels that are worth knowing about: Microphone Level. Line Level. Speaker Level.

What are the two types of audio?

Analog and digital audio formats are the results of two recording methods. They may not be confused with each other but often need to be explained in order for someone to understand their differences and values in audio production.

What does PA mean in audio?

Here's a brief rundown of what a PA system is: A public address system used to project sounds from instruments, voices and other acoustic sources. Comprises of microphones, mixers, amplifiers and loudspeakers.

What are the parts of a PA?

Public address systems consist of input sources (microphones, sound playback devices, etc.), amplifiers, control and monitoring equipment (e.g., LED indicator lights, VU meters, headphones), and loudspeakers.

What are the 6 characteristics of sound?

Sound wave can be described by five characteristics: Wavelength, Amplitude, Time-Period, Frequency and Velocity or Speed.

What is the film terminology for sound?

Soundtrack – all the different layers of sound used within a film, including location sound, dialogue, sound effects (FX), Foley sound, and musical score. Location sound (also known as production sound or direct sound) – sound recorded during production (filming).

What are the 3 types of sound?

Sound waves are characterized into three types. Audible sound waves are those that humans can hear. Infrasonic waves are those that are too low-frequency (below 20 Hz) for humans to hear. Ultrasonic sounds waves are those that are too high-frequency (above 20,000 Hz) for humans to hear.

What is acoustic terminology?

Acoustic Noise: any unwanted sound. Acoustic Frequency: a measure of the pitch of a sound, expressed in Hertz (abbreviated Hz) or cycles per second (cps). Acoustic Pressure: rapid fluctuations in the atmospheric air pressure at a point in space, expressed in microPascals (N/m2).

What science terminology involving sound and its production?

acoustics, the science concerned with the production, control, transmission, reception, and effects of sound. The term is derived from the Greek akoustos, meaning “heard.”

What are the three general types of audio used in a film?

The three essential categories of film sounds are dialogue, sound effects, and music. These three types of sound are crucial to the viewer.

What are the six properties of sound?

Sound is a longitudinal wave which consists of compressions and rarefactions travelling through a medium. Sound wave can be described by five characteristics: Wavelength, Amplitude, Time-Period, Frequency and Velocity or Speed. The minimum distance in which a sound wave repeats itself is called its wavelength.

What are the two main types of sound?

Sound has two basic forms: acoustic energy and mechanical energy. Each type of sound has to be tackled in their own way. Acoustic energy or sound is what we experience every day. It is in fact vibration of air (sound waves) which is transformed by the tympanic membrane in the ear of human to audible sounds.

What are sound waves called?

Sound waves are longitudinal waves. When longitudinal waves travel through any given medium, they also include compressions and rarefactions. Compression occurs when particles move close together creating regions of high pressure.

What are the 3 components of acoustics?

The entire spectrum can be divided into three sections: audio, ultrasonic, and infrasonic. The audio range falls between 20 Hz and 20,000 Hz. This range is important because its frequencies can be detected by the human ear.

What are the types of acoustics?

Question 1: What are the types of acoustics? Answer 1: There are different kinds of acoustics. They include environmental noise, musical acoustics, ultrasounds, infrasounds, vibration and dynamics.

What are acoustic techniques?

Acoustic methods (also known as sonic testing, vibration testing, mechanical impedance testing) depend on exciting vibrations in a specimen by a local impact and then measuring some properties of the vibrations, eg resonant frequency, decay time, etc.
