answer 2. Over a small region, an 'antiphase signal' can be used to cancel out a sound.
Regardless of the frequency of the wave, all sound:
Sound is measured in decibels, dB. Ten decibels (one Bel) sounds twice as loud as another sound. One decibel is the amount of sound just distinguishably louder than another sound. Named after A G Bell of telephone fame.
The fibres in a sponge move and trap/absorbthe sound instead of letting the sound travel to another place, that is a very simplified version.
The wavelength is equal to the local velocity of sound divided by the frequency, As with light, there can be refraction when sound passes from one medium to another with a different sound velocity.
It was when the air hit the wave and it move to another direction
True.
Destructive interference cancels out the sound - so all you hear is silence.
The loudness of sound waves that constructively interfere adds up, resulting in a louder sound. On the other hand, sound waves that destructively interfere cancel each other out, leading to a softer or quieter sound.
Yes they can. It's called destructive interference. When 2 sound waves converge on each other and the waves are 180 degrees out of phase then they will destructively interfere and the net effect will be the negation of both waves so you hear nothing.
When sound waves are in phase and interfere, their amplitudes add together, resulting in a louder sound. On the other hand, when sound waves are out of phase and interfere, they can cancel each other out, leading to a decrease in loudness or even silence, depending on the degree of cancellation.
Interference of sound waves occurs when one sound wave is not in phase with another. Graphically, this means that the sin/cos function representing the second wave does not line up exactly with the first one and the differences in sounds that result interfere with each other.
When sound waves interfere and result in quieter sound, it is known as destructive interference. This occurs when waves are out of phase and cancel each other out, reducing the overall amplitude of the sound.
No, light waves and sound waves cannot interfere with each other because they are different types of waves that travel through different mediums and have distinct properties. Light waves are electromagnetic waves that can interfere with each other, but they do not interfere with sound waves because sound waves are mechanical waves that require a medium (like air, water, or solids) to travel through.
louder
If two sound waves with the same frequency interfere in phase, they will reinforce each other, resulting in constructive interference. This will create a louder sound.
Beats in sound occur when two sound waves of slightly different frequencies interfere with each other, creating a pulsating effect of loud and soft sounds. This is because the waves temporarily reinforce and cancel each other out as they overlap in space. Beats are commonly heard when tuning musical instruments or from the interference between two close frequencies.
Nodes, which are points on the medium that remain stationary or have minimal displacement when two sound waves interfere to create standing waves.
