\u0130\u015fitme Sistemi, be\u015f ana b\u00f6l\u00fcmden olu\u015fur:<\/strong><\/p>\n

D\u0131\u015f kulak, orta kulak, i\u00e7 kulak, sinir yollar\u0131 ve beyin.<\/p>\n

D\u0131\u015f Kulak: <\/strong>Kulak kep\u00e7esi ve d\u0131\u015f kulak kanal\u0131ndan meydana gelir. Bu yap\u0131lar sesi toplar ve kulak zar\u0131na iletir.<\/p>\n

Orta Kulak: <\/strong>Zar ile i\u00e7 kulak aras\u0131nda bulunur. Zar ve kulak kemik\u00e7iklerini (\u00e7eki\u00e7, \u00f6rs, \u00fczengi) i\u00e7erir. Kulak zar\u0131ndaki titre\u015fimler, orta kulak bo\u015flu\u011funda bulunan bu \u00fc\u00e7 kemik\u00e7ik vas\u0131tas\u0131yla ses dalgalar\u0131 halinde i\u00e7 kula\u011fa iletilir. Bunu yaparken ayn\u0131 bir transformat\u00f6r gibi \u00e7al\u0131\u015f\u0131p sesi y\u00fckselterek aktar\u0131r.
Orta Kulakta da, aynen burunda oldu\u011fu gibi salg\u0131 bezleri, damarlar bulunur. \u00d6staki borusu ad\u0131 verilen bir boru ile genizle ba\u011flant\u0131l\u0131d\u0131r. Bu boru, orta kulaktaki hava bas\u0131nc\u0131n\u0131n d\u0131\u015f kulak yolundaki atmosfer bas\u0131nc\u0131na e\u015fitlenmesini sa\u011flar.<\/p>\n

\u0130\u00e7 Kulak: <\/strong>\u0130\u00e7 kulak, i\u00e7i s\u0131v\u0131 ve ince sinir u\u00e7lar\u0131yla dolu bir kemik kaps\u00fclden meydana gelmi\u015ftir. \u00c7ok ince bir zar ile kaplanm\u0131\u015f damarlar ile kanlanmaktad\u0131r. Bu kemik kaps\u00fcl i\u00e7erisindeki s\u0131v\u0131, kemik\u00e7ikler taraf\u0131ndan iletilen ses titre\u015fimleriyle harekete ge\u00e7irilir, b\u00f6ylece sinir u\u00e7lar\u0131 uyar\u0131l\u0131r.<\/p>\n

Sinir Yollar\u0131: <\/strong>\u0130\u00e7 kulakta uyar\u0131lan sinirler, bu uyar\u0131y\u0131 beyne ta\u015f\u0131r. Sinir, ince bir kemik kanal i\u00e7erisindedir. Ayn\u0131 kanalda, denge siniri ve y\u00fcz kaslar\u0131n\u0131 hareket ettiren y\u00fcz siniri de bulunur. Sinirler, kemik kanal i\u00e7erisinde, \u00e7ok ince kan damarlar\u0131 ile beslenirler.<\/p>\n

Beyin: <\/strong>\u00c7ok karma\u015f\u0131k ba\u011flant\u0131lar ve yollar kullan\u0131larak i\u00e7 kulaktan beyindeki i\u015fitme merkezine ula\u015ft\u0131r\u0131lan elektrik uyar\u0131lar\u0131 burada anlaml\u0131 ve anla\u015f\u0131l\u0131r ses haline getirilir.<\/p>\n

Sesin \u00d6l\u00e7\u00fcm\u00fc ve De\u011ferlendirilmesi;<\/strong> Ses, bilimsel olarak frekans\u0131 ve \u015fiddeti ile \u00f6l\u00e7\u00fcl\u00fcr. Sesin yo\u011funluk veya \u015fiddeti “desibel” cinsinden ifade edilir, saniyedeki titre\u015fim say\u0131s\u0131 ise frekans\u0131n\u0131 olu\u015fturur.<\/p>\n

Sesin Frekans\u0131 Nedir?<\/strong><\/p>\n

Sesin saniyedeki titre\u015fim say\u0131s\u0131 frekans\u0131d\u0131r. Ses, al\u00e7ak frekanslarda “kal\u0131n (pes)”, y\u00fcksek frekanslarda “ince (tiz)” duyulur. \u0130nsanlar saniyede 20 ile 20.000 titre\u015fim aras\u0131ndaki sesleri duyabilirler. Ancak insan\u0131n \u00e7\u0131kard\u0131\u011f\u0131 ses 300 ile 4000 frekans aras\u0131ndad\u0131r ve insanlar bu aradaki sesleri di\u011fer seslerden daha iyi duyarlar. \u0130\u015fitme kay\u0131plar\u0131n\u0131n pek \u00e7o\u011funda ilk \u00f6nce y\u00fcksek frekanslar etkilenir, bu sebepledir ki ki\u015filer \u00f6ncelikle ince sesli bayan ve \u00e7ocuklar\u0131n seslerini duymada zorlan\u0131rlar.<\/p>\n

Sesin \u015eiddeti Nedir? Desibel Nedir?<\/strong><\/p>\n

Sesin \u015fiddeti desibel (dB) cinsinden \u00f6l\u00e7\u00fcl\u00fcr. “0” desibel insan kula\u011f\u0131n\u0131n i\u015fitebilece\u011fi en d\u00fc\u015f\u00fck ses olarak kabul edilir. “180” dB ise roketin f\u0131rlat\u0131l\u0131\u015f an\u0131nda \u00e7\u0131kard\u0131\u011f\u0131 ses olarak \u00f6l\u00e7\u00fcl\u00fcr.
Desibeller logaritmik olarak artar ve azal\u0131r. Bu \u015fu anlama gelir. 20 dB, 10 dB’den 10 kat daha \u015fiddetlidir. 30 dB, 10 desibelden 100 kat daha \u015fiddetlidir.<\/p>\n

0 dB \u0130nsan kula\u011f\u0131n\u0131n duyabilece\u011fi en d\u00fc\u015f\u00fck ses
20- 30 dB F\u0131s\u0131lt\u0131, sessiz konu\u015fma
40- 60 dB Normal konu\u015fma, diki\u015f makinas\u0131, daktilo
60- 90 dB Ba\u011f\u0131rma sesi<\/p>\n

A\u015f\u0131r\u0131 y\u00fcksek seste kalman\u0131n \u00fcst s\u0131n\u0131rlar\u0131<\/strong><\/p>\n

90 -100 dB \u00fczeri A\u011f\u0131r vas\u0131ta trafi\u011fi; g\u00fcnl\u00fck maksimum 8 saat 100-120 dB Elektrikli testere, asfalt delme makinas\u0131; g\u00fcnde maximum iki saat
120-140 dB Y\u00fcksek sesli roket veya rock konserleri; g\u00fcnde maksimum 15 dakika
140 Silah sesi, jet motoru; kulaklara koruyucu kullanmadan izin verilmez. Kulaklarda a\u011fr\u0131, i\u015fitme kayb\u0131 ve \u00e7\u0131nlama olu\u015fturabilir.<\/p>\n
