What word describes the sound of an instrument based on the shape of the waveform of its sound?



Asked by: John Franklin

TimbreTimbre – the subjective quality of a sound as perceived by the listener.

What is the shape of a sound called?





All sound really is as vibrations of air molecules.

What is a waveform sound?

Term: Waveform (sound)



The generic term waveform means a graphical representation of the shape and form of a signal moving in a gaseous, liquid, or solid medium. For sound, the term describes a depiction of the pattern of sound pressure variation (or amplitude) in the time domain.

What is the term for an instrument that generate sound waves?

What is the term for an instrument that generates sound waves? Multiple Choice. Tripsillator.

What determines the shape of a waveform?

The shape of a wave is directly related to its spectral content, or the particular frequencies, amplitudes and phases of its components.

What best describes a sound wave?





For a sound wave traveling through air, the vibrations of the particles are best described as longitudinal. Longitudinal waves are waves in which the motion of the individual particles of the medium is in a direction that is parallel to the direction of energy transport.

How does the shape of an instrument affect its sound?

Although the pitch (how high or low a sound is) will be the same, a particular note sounds different on different instruments because they produce sound waves with different patterns (shapes and sizes). Bigger instruments tend to make lower and louder notes than small ones.

What waveform means?

A waveform is a representation of how alternating current (AC) varies with time. The most familiar AC waveform is the sine wave, which derives its name from the fact that the current or voltage varies with the sine of the elapsed time.

Is a wave a shape?

The shape of an ocean wave is often depicted as a sine wave, but the the experimental waveshape is described as a “trochoid”. A trochoid can be defined as the curve traced out by a point on a circle as the circle is rolled along a line. The following sketch is adapted from Bascom.

What are 3 types of waveform?

Each of the three basic waveform outputs, sinusoidal, triangular and square are simultaneously available from independent output terminals.



What is a radio waveform?

The Soldier Radio Waveform (SRW) is a Joint Tactical Radio System (JTRS) networking software that aims to provide voice, data, and video capabilities to small combat units and unmanned systems. SRW is the cornerstone of the Army’s lower tier tactical network.

Which of the following best describes sound waves quizlet?

Which of the following best describes sound waves? D. Two waves are traveling in a medium and arrive at a location at the same time.

What term best describes a sound wave that gets reflected?

Reflection of sound waves off of surfaces can lead to one of two phenomena – an echo or a reverberation.



Why is a sound wave called a longitudinal wave?

In longitudinal waves, particles of wave move in direction of propagation of waves. In a sound wave, the particles of the medium vibrate back and forth in the same direction of the disturbance. Therefore, sound wave is called a longitudinal wave.

What are such sound waves called?

A sound wave is called a longitudinal wave because compressions and rarefactions in the air produce it. The air particles vibrate parallel to the direction of propagation.

Why is sound wave called a mechanical wave?

Sound waves are mechanical waves because they need a material medium for propagation, like air or liquids like water, or metals like silver.

Why is a sound wave a mechanical wave?

Sound energy, or energy associated with the vibrations created by a vibrating source, requires a medium to travel, which makes sound energy a mechanical wave.



What type of mechanical wave is sound?

Longitudinal waves

There are two types of mechanical waves: Longitudinal waves – In this type of wave, the movement of the particles is parallel to the motion of the energy, i.e. the displacement of the medium is in the same direction in which the wave is moving. Example – Sound Waves, Pressure Waves.

What is sound what type of waves are sound waves in air?

longitudinal waves

Answer: a) Sound is defined as the form of energy which can be heard by us. Sound waves are longitudinal waves in air.
