by kim Updated: June 29, 2022

Decibel iyuniti yekuyera iyo inoshandiswa kuyera kusimba kwe rira. Inonyanya kushandiswa mukugadzira ruzha uye odhiyo engineering.

Decibel inodimburirwa se(dB), uye ndicho chimwe chezvinhu zvakakosha kana tasvika kune zvese kurekodha uye kutamba kwekurira.

Muchikamu chino, tichakurukura izvo zvekutanga zve decibel, kuti inoshanda sei uye kuti ungaishandisa sei kune mukana wako paunenge uchiita ruzha.

Tsanangudzo ye decibel

Iyo decibel (dB) inhengo yelogarithmic inoshandiswa kuyera nhanho yekumanikidza kweruzha (kukwidza kweruzha). Chikero che decibel hachina kunzwisiswa nekuti nzeve yemunhu inonzwa zvisingaite. Nzeve dzako dzinonzwa zvese kubva pamunwe wako uchikwesha zvishoma pamusoro peganda rako kune ine ruzha jet injini. Panyaya yesimba, ruzha rweinjini yejeti runenge rune simba rakapetwa ka1,000,000,000 kupfuura karuzha kadiki kanonzwika. Ndiwo mutsauko unopenga uye kuti isu tinyatso kusiyanisa misiyano yakakura kudaro musimba tinoda chiyero che decibel.

Chikero chedecibel chinoshandisa base-10 logarithmic kukosha kwereshiyo pakati pezviyero zviviri zvakasiyana zveacoustic: Sound Pressure Level (SPL) uye Sound Pressure (SP). SPL ndiyo yaunowanzo funga nezvayo kana uchifunga ruzha - inoyera kuti isimba rakadii rine ruzha pamusoro penzvimbo yakapihwa. SP, kune rumwe rutivi, inoyera kusiyana kwemhepo-kudzvanywa kunokonzerwa nemasaisai eruzha panzvimbo imwe chete mudenga. Mayero ese ari maviri akakosha zvakanyanya uye anoshandiswa kuyera ruzha mune chaiyo-yepasi maapplication senge studio yekurekodha kana maodhitoriyamu.

Decibel chikamu chimwe chegumi (1/10) cheBel icho chakatumidzwa zita raAlexander Graham Bell - muvambi Anthony Gray anotsanangura kuti "bhero rimwe rinoenderana sei neacoustic senitivity yakatenderedza 10-nguva huru kupfuura iyo vanhu vanogona kuona" - Nekupatsanura chikamu ichi kuita 10 zvikamu zvidiki isu tinokwanisa kuyera zvirinani misiyano midiki mukubuda kwe sonic uye kugonesa kuenzanisa kuri nyore pakati pematoni uye maumbirwo nekunyatsoita. Kazhinji 0 dB referensi nhanho ichareva kuti hapana ruzha runoonekwa, nepo 20 dB ichireva kufenda asi ruzha runonzwika; 40 dB inofanira kunge ichikwidza zvinonzwika asi isinganakidze kwenguva yakareba yekuteerera; 70-80 dB ichaisa zvakanyanya kushushikana pakunzwa kwako nepamusoro bhendi frequencies kutanga kukanganiswa kuburikidza nekuneta; pamusoro pe90-100dB unogona kutanga kuisa njodzi yekukuvadzwa zvachose kwekunzwa kwako kana yakafumurwa kwenguva yakareba pasina giya rekudzivirira rakakodzera.

Units dzekuyera

Mukugadzira ruzha, kuyerwa kunoshandiswa kuyera amplitude kana kusimba kwemafungu eruzha. Madecibel (dB) ndiwo anonyanya kushandiswa chiyero chekuyera paanenge achikurukura makwiriro eruzha uye anoshanda sechiyero chereferenzi kuenzanisa manzwi akasiyana. Ndiko kugona uku kunoita kuti tikwanise kuona kuti imwe ruzha rwakaita sei pane imwe.

Decibel rinotorwa kubva mumashoko maviri echiLatin: deci, zvinoreva chikamu chimwe-mugumi, uye belum, iro rakatumidzwa zita raAlexander Graham Bell mukuremekedza mipiro yake kuacoustics. Tsanangudzo yaro inopiwa se "chegumi chebhero" iyo inogona kutsanangurwa se "chikamu chekusimba kwenzwi".

Uwandu hwemanzwi ekudzvinyirirwa hunozivikanwa nenzeve dzevanhu hunodonha kubva pamusoro pe0 dB pamucheto wakaderera (usinganzwike) kusvika panosvika 160 dB kumucheto wepamusoro (chikumbaridzo chinorwadza). Decibel level yehurukuro yakanyarara pakati pevanhu vaviri vakagara mita imwe chete vakaparadzana ingangoita 60 dB. Kuzevezera kwakanyarara kungangoita makumi matatu dB uye avhareji yekucheka lawn inonyoresa pa30-90 dB zvichienderana nekuti iri kuyerwa kure sei.
