“First discovered by biophysicist Gerald Oster at Mount Sinai Hospital in New York City, brain wave audio technology sends pure, precisely tuned sound waves of different frequencies to your brain via stereo headphones. In his EEG research, Oster discovered that when different vibrations, or sound frequencies are delivered to the brain separately through each ear (as with stereo headphones), the two hemispheres of the brain function together to “hear” not the external sound signals, but a third phantom signal. This signal is called a binaural beat and it pulses at the exact mathematical difference between the two actual tones.”
“So, for example, if, simultaneously, a signal of 100 cycles per second entered your left ear and a signal of 109 cycles per second entered your right ear, what you would actually perceive you heard would be a rhythmic, soothing pulsation, beating at 9 cycles per second. Research results show that first parts of the brain and, eventually, large areas of the brain begin to resonate sympathetically with this “phantom” binaural beat in what is known as the Frequency Following Response.”
“Subsequent research determined that binaural beat frequencies could drive or guide brain activity into a wide variety of specific brain states. Thus, effortlessly and naturally, your brain activity slides into rhythm with this binaural beat, becoming organized and coherent. Within minutes, the sound frequencies start to balance the left and right hemispheres of your brain – creating a remarkable state called hemispheric synchronization and driving the electrical activity of your brain into powerful states, normally unattainable.”
“Scientists have noted that this rare phenomenon was accompanied by flashes of creative insight, euphoria, intensely focused concentration, deep calm, and enhanced learning abilities….Recent scientific research indicates that individual brain states, ranging from sleep to creativity, are marked by combinations of different brain wave frequencies.”

“A ringback tone, or audible ringing tone or ringback signal, is the audible ringing that is heard on the telephone line by the calling party after dialing and prior to the call being answered at the distant end. The ringback tone is different in various countries depending on the requirements for the ringback specification in those countries. … the standard ringback signal is generated by summing a 440Hz tone with a 480Hz tone and applying these to the telephone line in a 2 second on and 4 second off cadence. The tone combination produces a warbling “ring… ring…” sound, caused by the 40Hz beat between the two. Most other countries use a single tone, …The ringback signal may be generated by the called-party servicing switch or by the calling-party switch, but it is not generated by the called telephone instrument. It is generally started and stopped at the same rate as the ringing signal itself but perhaps out of phase.”
In recent years, “personalized ringback” tone has become globally popular. With this feature, callers will hear an audio selection applied to the telephone line that has been previously determined by the called party. Audio selections can include music, messages, and special effects. Equipment is installed in the telephone network to enable replacement of the standard ringback tone with a personalized audio selection. ..Various companies supply personalized ringback equipment for mobile phone and landline telephone companies….The use of such nonstandard telephony signals can cause problems with automatic dialing equipment such as faxes and modems, however lines intended to receive such data telephone calls normally have the proper ringback tone. In addition, a caller may define specific users to whom the personalized content will be played. Other callers will hear the “traditional” ringback tone.”

A ring tone is the sound made by a telephone to indicate an incoming call. The term, however, is most often used to refer to the customisable sounds available on mobile phones. This facility was originally provided so that people would be able to determine when their phone was ringing when in the company of other mobile phone owners.
A phone only rings when a special “ringing signal” is sent to it. For regular telephones, the ringing signal is a 90-volt 20-hertz AC wave generated by the switch to which the telephone is connected. For mobile phones, the ringing signal is a specific radio-frequency signal.
On August 5, 2006, the BBC reported that “Free ringtones” was the eighth most likely search term to return links to malware.
Malware is software designed to infiltrate or damage a computer system, without the owner’s informed consent. There are disagreements about the etymology of the term itself, the primary uncertainty being whether it is a portmanteau word (of “malicious” and “software“) or simply composed of the prefix “mal-” and the morpheme “ware”. Malware references the intent of the creator, rather than any particular features. It includes computer viruses, worms, Trojan horses, spyware, adware, and other malicious and unwanted software. In law, malware is sometimes known as a computer contaminant, for instance in the legal codes of California, West Virginia, and several other U.S. states.Malware should not be confused with defective software, that is, software which has a legitimate purpose but contains harmful bugs.

Whereas older telephones simply used a pair of bells for the ringer, modern ringtones have become extremely diverse, leading to phone personalization and customization.
Newer mobile phones allow the users to associate different ringtones for different phonebook entries. Many also allow users to create their own music tones, either with a “melody composer” or a sample/loop arranger…. Often these are native formats only available to one particular phone model or brand. However, other formats, such as MIDI or MP3, are often supported; they must be downloaded to the phone before they can be used as a normal ringtone. Commercial ringtones take advantage of this functionality, which has led to the success of the mobile music industry.
The Reproduction of Sound September 23, 2006

“The waveforms of sounds made by musical instruments and the human voice are very complex. The waveform can be illustrated as a graph, comparing the volume of the different frequencies or tones. Electronic devices often have problems involved in accurately reproducing those sounds.””A tuning fork is supposed to give off a pure tone of one frequency or note. Hearing a tuning fork is like looking at an object that is only one color. But just like most objects are multicolored, the sounds coming from most objects are very also very complex.”…..”A tuning fork would consist of only one bar or note. Of course, a true sound would have many more frequencies.”…
“Likewise, when a microphone records a sound, the some of the frequencies may be attenuated. This is especially true with inexpensive microphones. Such a microphone can severely distort the sound. One good example of a distorting microphone is the mouthpiece in most telephones.”…..After the microphone detects the sound, it goes through some electronics and is then reproduced and transmitted through loud speakers or headsets that consist of tiny speakers. Just like a microphone, the speakers also attenuate various frequencies and distort the sound coming out.”
Well-made speakers—which are usually more expensive—are the most faithful in reproducing the sound signal they receive. Since they often must produce amplified sound, speakers often have difficulty faithfully reproducing all frequencies…That is why better stereo systems have several types of speaker cones in one speaker box. They may have a tweeter—which is good at reproducing high notes—and a bass speaker for the lower frequencies… Some expensive car radios and stereo systems have what are called “equalizers” that show the volume of the different frequencies with rows of lights. Equalizers allow you to adjust the volume of these individual frequencies to overcome the attenuation of each note. This results in a sound that is closer to the original sound.
“Sounds from your voice or music are highly complex. There is distorting or attenuation of frequencies in the detecting and reproducing processes. Thus, the music you hear from the radio is never quite as good as if you would hear the original, live sound.”
What is Tone? September 22, 2006

Tone (music and acoustics)
Physically, a sound that is composed of discrete frequency (or sine-wave) components; psychologically, an auditory sensation that is characterized foremost by its pitch or pitches.
The physical definition distinguishes a tone from a noise, wherein the components form a continuum of frequencies. Tones may be pure, consisting of a single frequency, or they may be complex. Complex tones, in turn, may be periodic or not periodic. Periodic complex tones repeat themselves at rapid regular intervals. They have frequency components that are harmonics—discrete frequencies that are integer multiples of a fundamental frequency. For example, the tone of an oboe consists of a fundamental frequency of 440 hertz, a second harmonic component with a frequency of 880 Hz, a third harmonic at 1320 Hz, and so on. In general, musical instruments that generate continuous sounds—the bowed strings, the brasses, and the woodwinds—create such periodic tones. Tones that are not periodic (aperiodic) have frequency components that do not fit a harmonic series. Percussive instruments such as kettledrums and bells make such aperiodic tones.
Pitch is a sensation of highness or lowness that is the basic element of melody. Periodic complex tones tend to have a single pitch, which listeners will match by a pure tone having a frequency equal to the fundamental frequency of the periodic complex tone. Aperiodic complex tones tend to have multiple pitches. A second psychological attribute of complex tones is tone color or timbre. Tone color is often represented by descriptive adjectives. The adjectives may be linked to the physical spectrum. Thus, a tone with strong harmonics above 1000 Hz may be called “bright.” A tone with no harmonics at all above 1000 Hz may be called “dull” or “stuffy.”

Pitch
This is how high or low a sound seems. A bird makes a high pitch. A lion makes a low pitch.
Pitch and loudness are two ways that sounds are different. Another way is in quality. Some sounds are pleasant and some are a noise.Compare the two waves on the right.A pleasant sound has a regular wave pattern. The pattern is repeated over and over. But the waves of noise are irregular. They do not have a repeated pattern.
What is Entrainment? September 13, 2006

Resonant entrainment of oscillating systems
“Resonant entrainment of oscillating systems is a well-understood principle within the physical sciences. If a tuning fork designed to produce a frequency of 440 Hz is struck (causing it to oscillate) and then brought into the vicinity of another 440 Hz tuning fork, the second tuning fork will begin to oscillate. The first tuning fork is said to have entrained the second or caused it to resonate. The physics of entrainment apply to biosystems as well. Of interest here are the electromagnetic brain waves. The electrochemical activity of the brain results in the production of electromagnetic wave forms which can be objectively measured with sensitive equipment. Brain waves change frequencies based on neural activity within the brain. Because neural activity is electrochemical, brain function can be modified through the introduction of specific chemicals (drugs), by altering the brain’s electromagnetic environment through induction, or through resonant entrainment techniques.”
What is Healing by Sound Frequencies or Waves? September 12, 2006

“We can say that everything is made up of energy at various frequencies, that all things in nature vibrate to sound, light, color and resonate to same frequencies. Sound frequencies effect everything about us and correct vibrational frequencies can be used to heal and balance our bodies.””The body is just energy vibrating at different rates and frequencies. The chakra’s, bones, systems, organs, tissues, all possess a different resonant frequencies and are all vibrating at different rates creating a unique sound. Each person has a unique matrix of frequencies and tones, just like their own signature sound frequency.”
“When an organ or part of the body is vibrating out of tune or non harmoniously, it is called “dis-ease” or disease. Sound healing is all about identifying which frequencies are causing imbalance by being dissonant, out of balance, weak or diffused.”
“Sound healing works on the belief that the human body is not solid. Rather it is energy that is held together by sound. Any disease therefore indicates that some sound has gone out of tune. Sound is used in many forms to heal and balance energies, each chakra relates to a musical note and each color corresponds to one of the charka in our body.”
Playing a same note on a didgeridoo and other instruments will sound different due to the presence of higher frequency harmonics and overtones unique to each musical instrument. Speed: the horizontal speed of a point on a wave as it propagates in meters per second. The speed of sound waves in air is about 300 m/s.

Ancient Cultural and Sacred Sounds
Many ancient cultures recognize the importance of music and sound as a healing power.
*The Tibetans still use bells, chimes, bowls, and chanting as the foundation of their spiritual practice.
*In Indonesian traditional thinking, the Game lan is sacred and is believed to have supernatural power. The Gamelan, Gong and drum are used in ceremonies to uplift and send messages.
*The Australian Aboriginals and Native American shamanism use vocal toning and repetitive sound vibration with instruments created from nature in sacred ceremony to adjust any imbalance of the spirit, emotions or physical being.
*In Ancient Egypt, the Priests knew how to use vowel sounds to resonate their energy centers or chakra’s. There is a direct link between different parts of the body and specific sounds.”
