Faktor yang Bikin Orang Budek

Telinga merupakan indera yang penting bagi tubuh dan kelangsungan hidup. Namun, secara tidak sadar orang melakukan kegiatan yang dapat membahayakan indera pendengarannya. Apa saja faktor yang bisa bikin orang budek?

berikut 7 faktor yang bisa merusak dan membuat telingan budek:

1. Ear bud atau ear phone pada pemutar musik (music player)
Ear bud membuat suara menjadi lebih keras, sehingga untuk waktu lama dapat memekakkan telinga. Selain itu, ear bud juga membuat perubahan dalam sistem pendengaran. Bila orang terbiasa mendengarkan suara dari ear bud yang dekat dan keras, maka besar kemungkinan ia sulit mendengarkan suara pada level normal atau lembut.

2. Mobil terbuka (openkap)
Mengendarai mobil openkap membuat orang harus mendengar suara dengan level 88-90 Decibel (Db). Sebagai perbandingan, percakapan normal berada kisaran 50 Db, jalan lalu lintas sekitar 70 Db, mesin pemotong rumput sekitar 90 Db. Paparan berulang dari suara di atas 85 Db diketahui dapat menyebabkan kehilangan pendengaran permanen.

3. Obat-obatan
Salah satu efek samping yang kurang dikenal dari beberapa jenis obat, seperti obat nyeri, antibiotik tertentu dan obat kemoterapi berbasis platinum, adalah gangguan pendengaran.

4. Rokok
Satu pembuluh darah melayani koklea, yaitu organ telinga bagian dalam. Nikotin, vasokonstriktor yang menyebabkan pembuluh darah sedikit menyusut, dapat memiliki dampak yang luar biasa pada kapiler kecil yang melayani telinga.

5. Pekerjaan
Bidang pekerjaan seperti musisi, buruh pabrik, pekerja konstruksi dan pemadam kebakaran adalah beberapa orang yang berisiko tinggi untuk terpapar konstan terhadap suara keras.

6. Diabetes
Diabetes dapat menyebabkan penurunan aliran darah ke telinga. Pembuluh darah sempit atau abnormal akibat diabetes dapat mencegah darah mencapai koklea, juga dapat mencegah proses pembersihan racun. Ini memiliki potensi untuk merusak sel-sel lembut di dalam telinga.

7. Anemia sickle cell
Orang dengan anemia sickle cell sering mengalami kelelahan dan sakit karena sel-sel darah merahnya cacat yang berbentuk sabit tidak bulat. Padahal aliran darah normal penting untuk mencapai telinga.

he style has lived much longer than its Abercrombie clothing counterparts from the 1980s; it may be because of its relatively abercrombie Jeans inoffensive style or because people just love Abercrombie Pants animals, but it's less frowned upon.Today you can find high quality blanket and sheet Abercrombie Tees sets in a cheetah print. These are common enough that you could even go to a department store and find them, Abercrombie Shorts so you should have no problem finding cheetah printed sheets and blankets if they are what you are looking for. These can be a great accent to a more contemporary home theme Abercrombie Sweaters , though obviously are not great for homes that are more conservatively or classically decorated. Curtains that have this type of pattern are more difficult to come by.
