Lub amplitude ntawm a suab nthwv dej txiav txim nws suab nrov los yog ntim. Lub amplitude loj dua txhais tau hais tias nrov dua suab , thiab me me amplitude txhais tau tias softer suab . Hauv daim duab 10.2 suab C yog nrov tshaj suab B. Thevibration ntawm ib qhov chaw teev lub amplitude ntawm ib nthwv dej.

Dhau li ntawm no, peb hu li cas lub suab nrov lossis softness?

Teb thiab piav qhia: Lub nrov los yog softness ntawm a suab yog hu ua nws ntim . Tus nqi ntawm kev siv a suab yoj tau ua rau nws suab louder lossis softer. Intensity yog ntsuas nyob rau hauv decibel units. Qhov ntau decibels, qhov siab ntawm qhov siv suab thiab lub 'louder' nws suab rau peb.

Tsis tas li ntawd, dab tsi txiav txim siab lub suab zoo? Suab " zoo "los yog "timbre" piav txog cov yam ntxwv ntawm suab uas tso cai rau lub pob ntseg kom paub qhov txawv suab uas muaj tib lub suab thiab nrov. Timbre yog qhov tseem ceeb txiav txim siab los ntawm cov ntsiab lus harmonic ntawm a suab thiab dynamic yam ntxwv ntawm lub suab xws li vibrato thiab lub hnab ntawv tawm tsam- lwj ntawm lub suab.

Tsuas yog li ntawd, qhov ntim ntawm lub suab yog dab tsi?

Kev siv zog yog ntsuas nyob rau hauv units ntawm lub zog nyob rau hauv cheeb tsam thiab lub sij hawm. Thaum tham txog suab wave, ua ntim yog kev xaav ntawm nrov nrov los ntawm kev siv ntawm a suab yoj. Qhov siab dua qhov siv ntawm a suab , qhov nrov nws yog perceived nyob rau hauv peb pob ntseg, thiab siab dua ntim nws.

Dab tsi yog 3 yam ntxwv ntawm lub suab?

Lub suab nthwv dej feem ntau yooj yim rau kev piav qhia nyob rau hauv cov nqe lus ntawm sinusoidal dav hlau nthwv dej, uas yog yam ntxwv los ntawm cov genericproperties:

  • Zaus, los yog nws inverse, wavelength.
  • Amplitude, suab siab los yog siv zog.
  • Ceev lub suab.
  • Kev taw qhia.
