Nziyo dzeMimhanzi: kushanda acoustics

Kuteerera kurongeka kwevamunofarira mimhanzi, hapana munhu anofunga nezvemifananidzo inosangana neHertz, decibels, watts, frequencies uye kunyange neCGI. Zvisinei, kuchena kwekubereka, inzwi guru uye hupfumi hwehuzha hunobva kune avo. Hazvigoneki kutaurirana zvisingazivikanwi kuti iye ane simba rose ndiyewo anonyanya kushanda acoustics.

Zviratidzo zvekunzwa kwevanhu uye kusarudzwa kwevatauri

Inzwi rinonzi ma mechanical vibrations yezvinhu zvekudenga, izvo zvinogona kukonzera mamwe manzwiro muuropi hwevanhu. Inokurumidza kupararira kwemafungu aya kunobva pauwandu hwemvura, huni, simbi kana mhepo yavanofamba nayo. Masayendisiti akaratidza kuti vanhu vanonzwisisa nenzeve chete humwe hurumende dzinonzwika: kubva 20 Hz kusvika 22 kHz. Chikamu chepasi chemuganhu ndeye-infra-waves (yakadzika kwazvo), iyo yakakwirira-ultrasound (yakakwirira kwazvo). Sezvazvinonzwisisika, mazairo nemitengo yakakura kana kuti pasi kudarika idzi nhamba, nzeve dzedu hadzinganzwisisiki.

Mimhanzi uye teknolojia yemazuva ano

Nhamba yakakosha yehutachiona-hutachiona hutatu hwakakamurwa kuva mapoka matatu nenyanzvi.

Yokutanga ndiyo inonzi "pfungwa" hurukuro, iyo inoparidzira mutauro kana mimhanzi mune imwe nzira.

Boka rechipiri rinosanganisira zvirongwa zve emitters ayo nyanga dzinotarisirwa kushanda kune imwe nzvimbo: migwagwa kana nzvimbo.

Chikamu chechitatu chinosanganisira kushanda acoustics, nehurongwa hwekugovera zvinyorwa zvinyorwa pamiganhu yakati:

• Ndizvo chete pamasvingo akafanana;
• Pane rumwe rusvingo;
• Pamusoro pedenga uye pamadziro;

Linear inoshanda acoustics hi-fi inoshandiswawo mumasangano akazaruka, zvose kumba uye muvharo dzevharo.

Ichokwadi here kuti iye anowedzera simba mukurukuri, kunyanya mimhanzi inonzwika?

Iyo yakanakisisa inoshanda acoustics ichakurumidza kubvisa zororo uye kurara kwemhuri dzemhuri nziyo dzisina matsi. Zvisinei, simba rekuita harina chokuita nazvo. Izvi zvinoratidzika, panzvimbo pacho, nemagetsi ekuvimbika kwehurongwa: pamusoro pechimiro, ichashanda kwenguva refu. Uye zvisinei simba remugadziridziro rinofanira kunge risina kukosha kudarika simba revatauri, zvisinei kuti mimhanzi ichakurumidzira kumira, sezvo hurukuro inogona kupisa uye kupisa.

Muzvokwadi, ruzha rwekutamba harukurudzirwi nesimba, asi nehutano hwekunzwisisa hwevatauri, hunotaridzwa ne decibels. Nhamba ye 85 dB yakanyatsokodzera midziyo yemimhanzi yakaiswa muimba yacho.

Imwe inokosha parameter ndiyo inowanzo inonyorwa. Imba acoustics (inoshanda kana kuti isina kutenderera) inofanira kuva nechese-frequency speakers, uye yepamusoro-nguva, uye pakati pepakati hurukuro. Kuvapo kwehuwandu hwemashoko emimhanzi kuchaita kuti huwedzere kuzadzwa, uye kuteerera kunounza mufaro mukuru.

"Yakatsvaga" maitiro - ndeye joke!

Ichokwadi, acoustics iri kushanda, sekusimudzira, haina bhanji, asi bhaning. Kana pane mumwe chete mukurukuri muimba - iyi ibhi rimwe-bhuru kana kuparadzira bhurukuro, maviri (rimwe neLF neMF, uye imwe neHF) - mbiri-nzira. Vadzidzi vane ruzivo rwemimhanzi vanozvidzivirira ivo pachavo, vatatu- uye kunyange mahlanu-band audio systems, umo imwe imwe yeshongwe yakagadzirwa ne beepers inobereka inzwi rechechi yakasiyana. Chimwe chezvikwata zvebandauriri ndezvekuvapo kwezvakavakwa-mumatsvina zvinokonzera mafungu emhepo anowanikwa kune nzeve dzevanhu.

Kushanda hi-fi acoustics kazhinji kunosanganisira unit huru, bass subwoofers uye mashoma satelliti maduku.

Kutenga gadziriro yakagadzirwa, zvakakosha kubhadhara kutarisa kwekate. Inofanira kunge yakaita zvinhu zvakadai se:

• Subwoofer + hurukuro;
• Pair kumashure uye pamberi pevatauriri;
• Central unit with loudspeaker.

Acoustics inoshanda kumusha yemitambo inofanira kunge yakagadzirwa nezera rinotevera. Izvi zvichaita kuti chiitiko chekunyudzwa kuzere mumamiriro okunze.

Matanda kana mapurasitiki?

Paunosarudza mimhanzi, teerera mashoko ekugadzira nyaya yevakurukuri. Mazuva ano mashizha ari pasi acoustics anonyanya kuiswa mumabhokisi e-phase-inverter type. Kuti kuve nemuviri wemapurisa, zvose matanda uye mapurasitiki zvinoshandiswa. Zviri nani kana nyaya yacho isina kumira, isina mashizha emhepo uye nehutano hwakanaka. Izvo zvisiri zvemalasitiki epurasitiki ndeyekutengesa nekuwedzera kukuru kwehuwandu, kusvibiswa kwemashoko. Nokudaro, humwe hutachiona huri nani kune avo vanotaura nezvemakombiyuta, vanogadzira vagara vaiswa mumabhokisi ematanda anovimbika.

Nzira yekuita sei zvakajeka zvezvinhu zvemukurukuri system muimba?

Unhu hwakanaka hwokuteerera mimhanzi makamuri anogadzirisa zvinotevera zvinodiwa:

• Kutadza kwe "kuputika" kunyoresa uye kugadzikana kwekunzwa kwemunharaunda;
• Kuparadzanisa kwakasiyana kwemazwi ane simba mukati memukamuri;
• Kuderedza kudengenyeka kwemheremhere.

Paunenge uchigadzirira imwe nzvimbo yekuisa zvigadzirwa zvekutumbuka, zvakakosha kuyeuka kuti nzvimbo yepasvingo dzakatarisana haifaniri kunge yakanyatsonaka uye yakafanana. Kana zvisina kudaro, manzwi acho acharatidzwa kubva kwavari, kufanana nemabhora, achigadzira mamiriro echo chinyorwa chisina kusimbiswa chinozoita kuti mhando dzomumhanzi dzive chinhu chimwe chinoramba chichiridza nekurira kwefoni. Nyemba, pilasters, zvigadziri zvinyoro zvakanyatsonaka pakugadzira kufungisisa kwakanyanya nekuvandudza kuparadzanisa.

Kana mauto akada kuimba rwiyo, zvakakosha kufunga nezvekuisa maikorofoni muimba. Zvakakosha kuronga iyo nenzira yekudzivisa kuzvidzora kwemasimba. Kana zvisina kudaro, pane kuimba, iwe unofanira kuteerera squeak uye screech yevakurukuri.

Apo inoshanda acoustics inogadzirirwa muimba yakagadzirirwa, hutano hwezwi hunofananidzwa nematongerwo akaparidzirwa uye apo kuteerera kunonunura kunzwisisika kunoshamisa.
