What can make a sonic boom?
Most military combat aircraft can make a sonic boom, even space shuttles. The aircraft flies up to Mach 2, twice as fast as the speed of sound and can travel more than one thousands miles per hour, which is much faster than the speed of sound. A supersonic passenger aircraft can also beat the speed of sound (it is called air France the Concorde). A supersonic boat can also make a sonic boom and there are even supersonic cars the fastest land vehicle. There is a Russian supersonic bomber called the Tu-160 Blackjack and the United States has a supersonic bomber called the B-1 bomber.
How do beats help determine whether two sound waves are the same frequency?
A sound known as a "beat frequency" will be heard when two sounds of almost (but not quite) the same frequency are mixed together. This is commonly heard when tuning a stringed instrument (such as a guitar) into itself, or when tuning to a standard pitch generator. If the string is vibrating at exactly the same frequency as the standard, then no beat frequency is heard. If the string is vibrating at a just slightly different frequency from the standard, then the interference between the two sounds is heard as a regular "beat". The frequency of the beat is exactly equal to the difference between the two frequencies i.e. if the standard is 440 Hz and the string is vibrating at 441 Hz, then a beat frequency of 1 Hz will be heard.
What would the beat frequency be if you added tones of 880 Hz and 882 Hz?
The number of beats that we hear per second is the beat frequency. It is equal to the difference in the frequencies of the two notes. In this case: Beat frequency = 882 Hz - 880 Hz = 2 Hz. This means that we will hear the sound getting louder and softer 2 times per second.
What is the eardrum it vibrates when sound waves strike it?
Even soft sound makes the eardrum vibrate. It's the sound pressure deviation we measure as sound pressure level (SPL). The threshold of pain is known in acoustics as the lowest strength of a stimulus that is perceived by the ear as painful. Because of the different sensitivity of the hearing of people it cannot be given an accurate value. You can find the following rounded values for threshold of pain in various audio articles and books: 140 dB equivalent to SPL 200 Pa 137.5 dBSPL equivalent to 150 Pa 134 dBSPLequivalent to 100 Pa 130 dBSPL equivalent to 63 Pa 120 dBSPL equivalent to 20 Pa Sound pressure levels more than 140 dB will let your eardrums burst.
An airplane mechanic notices that the sound from a twin-engine aircraft rapidly varies in loudness when both engines are running What could be causing this variation from loud to soft?
The engines are running at slightly different frequencies, so their sounds combine to make beat notes whose amplitudes vary quickly.
What is a mark for no sound to count as a beat?
even no sounds counts as a heart beat
How does kiba beat the sound guy?

How many counts are there in a crotchet?
Crotchet= 1 beat
How many counts does a semiquaver have?

What does the word beat refer to in sound?
The term "beat" in sound or music refers to the rhythmical repetition of a sound or sounds.
Does beat have a long or short vowel sound?
The EA pair in beat has a long E sound, as in cheat, meat, and seat.
How many counts does an eighth note get?
An eighth note is worth half a beat.
How can you beat a warriors of chaos army with vampire counts?
with skill and a touch of magic :)
Is beat long vowel sound?
Yes, "beat" has a long vowel sound in English. The "ea" combination creates the long e sound.
What is a sound of a drum?
the beat
Does beat have a short vowel sound?
No. The EA pair in beat has a long E sound, as in cheat, meat, and seat.
A crotchet last for how may counts?
If the time signature is for crotchets, a crotchet lasts one beat.
