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.
Why Would WHO Do This If There Weren’t a Recognized Problem? (Even if they won’t admit it yet) September 5, 2006

Electromagnetic fields 
“Electromagnetic fields of all frequencies represent one of the most common and fastest growing environmental influences, about which anxiety and speculation are spreading. All populations are now exposed to varying degrees of EMF, and the levels will continue to increase as technology advances.”
“As part of its Charter to protect public health and in response to public concern, the World Health Organization (WHO) established the International EMF Project in 1996 to assess the scientific evidence of possible health effects of EMF in the frequency range from 0 to 300 GHz.”
“The EMF Project is open to broad participation.”
“The EMF Project is open to any WHO Member State government, i.e. department of health, or representatives of other national institutions concerned with radiation protection. The project is fully funded by participating countries and agencies.”

..”the human ear is capable of detecting sound waves with a wide range of frequencies, ranging between approximately 20 Hz to 20 000 Hz. Any sound with a frequency below the audible range of hearing (i.e., less than 20 Hz) is known as an infrasound and any sound with a frequency above the audible range of hearing (i.e., more than 20 000 Hz) is known as an ultrasound. Humans are not alone in their ability to detect a wide range of frequencies. Dogs can detect frequencies as low as approximately 50 Hz and as high as 45 000 Hz. Cats can detect frequencies as low as approximately 45 Hz and as high as 85 000 Hz. Bats, who are essentially blind and must rely on sound echolocation for navigation and hunting, can detect frequencies as high as 120 000 Hz. Dolphins can detect frequencies as high as 200 000 Hz. While dogs, cats, bats, and dolphins have an unusual ability to detect ultrasound, an elephant possesses the unusual ability to detect infrasound, having an audible range from approximately 5 Hz to approximately 10 000 Hz.”
