She seems dressed in all of me, stretched across my shame.
All the torment and the pain, leaked through and covered me.
I'd do anything to have her to myself, just to have her for myself.

Now I don't know what to do, I don't know what to do when she makes me sad.

She is everything to me, the unrequited dream.
A song that no one sings, the unattainable.
She's a myth that I have to believe in, all I need to make it real - is one more reason.

I don't know what to do, I don't know what to do when she makes me sad.

But I won't let this build up inside of me, I won't let this build up inside of me.

I catch in my throat - choke!
Torn into pieces I won't.
No, I don't want to be this.

But I won't let this build up inside of me, I won't let this build up inside of me.

She isn't real.
I can't make her real...

The ear is an amazing body part because it enables humans and animals to hear what goes on around them. Hearing is one of the five senses of the body. The ears help the body to pick up sound waves and vibrations. Sound travels in waves through the air, the ground, and various other substances. Sound cannot be seen, but it can be felt by vibrations. The number of vibrations that are produced per second is called frequency. Frequency varies for each sound and is measured in hertz. One hertz is equal to one vibration per second. A sound with a low frequency will have a low pitch, such as a human's heartbeat. A sound with a high frequency will have a high pitch, such as a dog whistle. Humans cannot hear sounds of every frequency. The range of hearing for a healthy young person is 20 to 20,000 hertz. The hearing range of humans gets worse with age. People lose the ability to hear sounds of high frequency as they get older. The highest frequency that a normal middle-aged adult can hear is only 12-14 kilohertz. Also, the hearing range for men worsens more quickly than the hearing range for women. This means that women will have the ability to hear notes of higher pitch than men of the same age do. What is sound and frequency? Sound is a longitudinal mechanical wave of any frequency. Frequency is the number of cycles, or complete vibration experienced at each point per unit. Frequency is measured in hertz. The hertz, Hz, is the derived SI unit of frequency. The frequency of a sound wave determines its tone and pitch. The frequency range of a young person is about 20 to 20,000 hertz. The human ear is capable of hearing many of the sounds produced in nature, but certainly not all. Some low frequencies like a heart beat of 1 or 2 Hz can not be heard, just like sonar sounds produced by dolphins which are too high. Any frequency that is below the human range is known as infrasound. It is so low that it may be detected by a creature with big ears, such as an Elephant.
