School Regular and irregular waves belong to the same physical phenomenon and acoustic music are equally important. The intensity level of sound, popularly known volume is measured in decibels (SD). The greater the number of dB higher intensity level (higher volume) increasing the amplitude of the sound wave, see below: Wave amplitude There are laws that regulate the emission of sounds in regions inhabited and devices that measure their intensities therefore from 120 Db the human ear can suffer irreparable damage. However, these laws are not always enforced. One of the major problems of cities is noise pollution, which can bring great damage to people's health through stress or other disorders. Read about this subject, too, in 06 sheets. search You can search with colleagues the following subjects: How do you measure the volume of sound? Who created and when did this measurement? What is the speed of sound in different materials? When the man got with machines, overcome this limit? How is the Brazilian legislation regarding the use of sound rules and penalties? How is your soundscape? Your city is very noisy? The number of people talking together in the classroom may be harming you, your colleagues and the work of teachers? And its noise contribution is positive or negative? Think about it. Formal Elements

Škola Redovite i neredovite valova pripadaju istom fizičkom pojavom i akustične glazbe su jednako važni. Intenzitet razina zvuka, popularno poznat volumen se mjeri u decibelima (SD). Veći broj dB visokog intenziteta razini (veći volumen) povećanjem amplitude zvučnog vala, pogledajte u nastavku: Val amplituda Postoje zakoni koji reguliraju emisije zvukova u područjima naseljenim i uređaje koji mjere njihove intenzitete stoga od 120 dB ljudsko uho može pretrpjeti nenadoknadivu štetu. Međutim, ovi zakoni se ne provode uvijek. Jedan od glavnih problema u gradovima je buke, što može donijeti veliku štetu za zdravlje ljudi kroz stres ili druge poremećaje. Pročitajte o ovoj temi, također, u 06 listova. Usporedite Možete tražiti s kolegama iz sljedećih predmeta: Kako mjeriti glasnoću zvuka? Tko je stvorio i kada je ovo mjerenje? Što je brzina zvuka u različitim materijalima? Kad je čovjek dobio sa strojevima, prevladati tu granicu? Kako je brazilski zakonodavstvo vezano uz korištenje zvučnih pravila i kazne? Kako je tvoja zvukovlje? Vaš grad je vrlo glasan? Broj ljudi pričaju zajedno u razredu može vam šteti, svoje kolege i rad nastavnika? I njegov buke doprinos je pozitivna ili negativna? Razmislite o tome. formalni elementi
