Syn. 1. belabor, batter, drub, maul, baste, pommel, cudgel, buffet, flog. BEAT, HIT, POUND, STRIKE, THRASH refer to the giving of a blow or blows. BEAT implies the giving of repeated blows: to beat a rug. To HIT is usually to give a single blow, definitely directed: to hit a ball. To POUND is to give heavy and repeated blows, often with the fist: to pound a nail, the table. To STRIKE is to give one or more forceful blows suddenly or swiftly: to strike a gong. To THRASH implies inflicting repeated blows as punishment, to show superior strength, and the like: to thrash a child. 12. conquer, subdue, vanquish, overpower. 14. excel, outdo, surpass. 22. See pulsate.

In physics, the pulsation resulting from a combination of two waves of slightly different frequency.

Beat frequency is the difference between the frequencies of the combining waves. When the interfering frequencies are in the audible range, the beats are heard as alternating soft and loud pulses. The human ear can detect beats with frequencies up to 10 hertz, or 10 beats per second. Piano tuners listen for beats when comparing the pitch of a tuning fork to that of a vibrating string; when no beats are heard, the fork and string are at the same frequency. Ultrasonic or inaudible frequencies can be superimposed to produce audible beats, allowing the detection of vocal sounds produced by bats or dolphins.

music
      in music, the basic rhythmic unit of a measure, or bar, not to be confused with rhythm as such; nor is the beat necessarily identical with the underlying pulse of a given piece of music, which may extend over more than a single beat. The number and relative positions of accented and unaccented beats furnish the basis of proper metric articulation, with the strongest accent usually falling on the first beat after the bar line. In Western musical notation the number of beats to the measure is indicated by the upper figure of the time signature at the beginning of a musical composition, while the time value of each separate beat (e.g., a quarter or eighth note) is indicated by the lower figure. See also metre; rhythm.

waves
 in physics, the pulsation caused by the combination of two waves of slightly different frequencies. The principle of beats for sound waves can be demonstrated on a piano by striking a white key and an adjacent black key at the bass end of the keyboard. The resulting sound is alternately soft and loud—that is, having characteristic pulsations, or throbs, called beats. Toward the treble end of the keyboard, the beat frequency is greater because the difference in frequency of adjacent keys is more than at the lower end. The Figure—> depicts two waves n1 and n2 with respective frequencies of 24 and 30 vibrations per second (hertz); the beat frequency N is their difference, 6 beats per second.

      The phenomenon of beats is employed in various ways. For example, in the tuning (tuning and temperament) of instruments, if a tuning fork and piano key of the same note are struck simultaneously and no beat is heard, then they are of identical pitch. Ultrasonic vibrations (having a frequency higher than is audible), such as the vocal sounds made by bats and dolphins, may be detected by superimposing a sound of different frequency to produce audible beats. The principle is also used in the superheterodyne reception of radio waves, in which a low-frequency signal from an oscillator is beat against an incoming high-frequency radio signal to produce an intermediate (beat) frequency that can be amplified to produce audible signals.
