One ancient TCM text expressed the power and importance of Yin and Yang this way: âIf you can understand Yin and Yang you can hold the universe in your hands.â How Yin and Yang Apply to You and Your Life. You might be wondering how Yin and Yang apply to you and your life, and to any health issues you might have.
Sound pressure is measured in decibels (dB). Like a temperature scale, the decibel scale goes below zero. The average person can hear sounds down to about 0 dB, the level of rustling leaves. Some people with very good hearing can hear sounds down to -15 dB. If a sound reaches 85 dB or stronger, it can cause permanent damage to your hearing. The amount of time you listen to a sound affects how much damage it will cause. The quieter the sound, the longer you can listen to it safely.
Introduction. Hyperacusis is an extreme aversion and hypersensitivity to sounds that are generally not an issue to others. Electrical and machine noises, as well as sudden high-pitched noises, are usually hard to tolerate for people with hyperacusis (examples are listed in the box on this page). However, any sound can potentially trigger a reaction in someone with hyperacusis â even the sound of their own voice.
