HODISAHOI OVOZY

Az bayni hodisahoi tabii dar hayoti inson hodisahoi ovozy (va yo ovoz) ahamiyati vija dorad. Olame, ki mo dar on zindagi mekunem, az ovozhoi gunogun pur ast. Honishi parrandagon, musiqy, sadoi obi juy, khishirrosi bargho, radu barq in hama ovozhoi gunogun meboshand.

Nutqi mo niz az yak qator ovozhoi yake pasi digar oyanda iborat meboshad. Mo ba osoni ovozi yak shakhsro az ovozi shakhsi digar farq mekunem.

Aknun dar borai chi tavr paydo shudani ovoz tavaqquf mekunem. Hamon tavre tajribahoi sodda nishon dodand, jismhoi sadodihanda hamesha mejumband.

rezonator

Agar mo tori gitor va yo qomuzro andak kashida, onro cap dihem, pas mo ovozro meshunavem.

Mo mebinem, ki miyoni tor guyo gafs va shaklu namudi on nomafhum shudaast. Namudi qomuzi sadodihanda tagyir yoftaast, zero vay mejumbad.

Agar torro ba dast bigirem, jumbish tavaqquf karda, hamzamon sado niz az bayn meravad.

Sarchashmai ovoz jismhoi larzanda ba shumor meravand.

Hangomi omuzishi hodisahoi ovozi va jur kardani sozhoi musiqi kamerton istifoda meshavad (rasmi 35). Agar ba kamerton tavassuti putki reziny ohistakak bikubem, vay shuru ba larzidan va sado barovardan mekunad. Agar kamertoni sadodihandaro dar dast bigirem, pas ovozi on suct meshavad. Vale agar onro ba kuttii takhtagin guzorem, ovoz baland megardad. Zero dar natijai larzish ham dar qutti va ham gavgoi havoi dar on buda, ovoz paydo meshavad.

Jicme, ki ba ovoz aksulamal nishon medihad, rezonator nomida meshavad.

Rezonatorhoi coxne shaklhoi gunogun dar sozhoi musiqi istifoda meshavand. Tavri misol, dar qomuz onro korpus menomand. Hangomi larzishi torho vay ovozro yakchand marotiba baland menamoyad. Hamchun sarchashmai ovozi inson va bisyor hayvonho payvandakhoi ovozii onho hidmat mekunand.

Tahti tasiri berun shudani jarayoni havo az shush, payvandakhoi ovozii odam jumbida, ovozi zaifu suet mebarorad. In ovoz tavassuti rezonatorho, yane halqum va javfi dahon guzashta qavi megardad. Azbaski sokhtori har yak odam va hayvon gunogun ast, ovozi onho niz gunogun meboshad.

Agar hangomi dar havo pahn shudan ovoz bo kadom yak moneaho duchor meoyad, qullaho, devorho), pas vay az on aksi sado mebarorad va mo ovozi inikosshudaro meshunavem. In hodisaro aksi sado menomand.

Misol meovarem. Avval kutoh «Oo!» meguem. Dar masofai dur az 10 m az moBaroy on ki ovozi sarchashma va ovozi inikosshuda tav­ri chudogona shunida shavad, boyad fosilai zamony bayni onho na kam az 1/15 soniya boshad.

S YUm _1_ boyad moneae mavjud boshad. In masofaro ovoz dar muddati 1 v 340 m 34 soniya tay menamoyad.

To ba in ki ovozi aksshuda barmegardad, hamon qadar vaqt meguzarad. Pas ovozi aksshuda to ba mo pas az 1/34 soniya • 2=1/17 soniya barmegardad. In az on vaqte, ki mo dar bolo ishora kardem, kamtar meboshad.

Az in ru, ovozi aksshudaro mo shunida nametavonem. Vale ovozi kutoh ifodakardai «Oo!» hamchun «Oo-o-o!» beshtar sado medihad. Agar dar tolori kalon odami kam dast, pas ovozi odami guyandaro dakiq shunidan nomumkin ast. Zero sukhanoni shakhsi guyanda yakchand marotiba dar ashyoi gunogun, chun devorho, kharakho va digar jinshoi sakht barkhurda, to ba gushi odami shunavanda dar vaqthoi gunogun merasad.

Agar dar hamon tolor odamoni bayni hamdigar suhbatkunanda biser boshand, onro barmalo shunidan mumkin ast, zero ovozhoi inikosshuda kam buda, ovozhoi jazbshuda biser meboshand. Kalimaho ba gushi odami shunavanda hamzamon rasida, saheh shunida meshavad.
