“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.”

“Beta waves range between 13-40 HZ. The beta state is associated with peak-concentration, heightened alertness and visual acuity….. 40HZ beta frequency may be key to the act of cognition.”

Alpha waves range between 7-12 HZ. This is a place of deep relaxation, but-not quite meditation. In Alpha, we begin to access the wealth of creativity-that lies just below our conscious awareness – it is the gateway, the entry-point that leads into deeper states of consciousness. Alpha is also the home-of the window frequency known as the Schuman Resonance, which is the-resonant frequency of the earth’s electromagnetic field.

Theta waves range between 4-7 HZ. Theta is one of the more elusive and-extraordinary realms we can explore. It is also known as the twilight state-which we normally only experience fleetingly as we rise up out of the depths-of delta upon waking, or drifting off to sleep. In theta we are in a waking-dream, vivid imagery flashes before the mind’s eye and we are receptive to-information beyond our normal conscious awareness. Theta has also been-identified as the gateway to learning and memory. Theta meditation increases-creativity, enhances learning, reduces stress and awakens intuition and-other extrasensory perception skills.

Delta waves range between 0-4 HZ. Delta is associated with deep sleep. In-addition, certain frequencies in the delta range trigger the release of-Growth Hormone beneficial for healing and regeneration. This is why sleep,-deep restorative sleep is so essential to the healing process.
