How to cut noise in a plane cabin Are there ways to get some peace from that incessant droning noise during your flight? Katia Moskvitch finds out. www.bbc.com The noise during a typical plane journey can vary significantly. Take-off and landing are the loudest moments, when noise levels inside the cabin can reach 105 decibels . At cruising altitudes, noise drops to around 85 dB, says Pamela Mason of the American Speech-Language-Hearing Association . Long exposure to 85 dB can cause temporary hearing problems. "Many people notice tinnitus – ringing in the ear – following a long flight, an early symptom of noise damage," says Mason. And if noise goes higher than 90 dB for eight or more hours per day, it may lead to permanent hearing loss, warns the US Federal Aviation Authority . On older aircraft, or towards the back of a plane, noise levels can often get close to this threshold. Uçak türüne göre 105 ila 85 desibel arası.

Bir projem var. Proje için günümüz yolcu uçaklarının kabin içinde uğultu sesi kaç dB kadar işitilir bilmem gerekiyor. Eğer bilen biri yardımcı olursa çok sevinirim.

Rica ederim.
