Audio in the region of 20Hz-20Khz can create psychological disturbance in individuals at levels substantially below those required for bodily discomfort or trauma.
From the thunderous hypnotic drumming of Zulu warriors to riot police beating their batons on shields whilst marching towards confrontation, the psychological effects of sound have been used extensively throughout history as a warfare device. Noise has always been experienced as ‘destruction, disorder, dirt, pollution, and aggression’. All cultures associate noise with the idea of the weapon, blasphemy and plague. “Behold, I will bring evil upon this place, the which whosoever heareth, his ears shall tingle” (Jeremiah 19.3)”. “When the drums of the resurrection sounded, they filled the ears with fear” (Al-Din Runir, Diavani, Shansi Tabriz).
Recently, psycho-acoustic warfare was allegedly used in the Waco siege at the Davidian compound in Texas, where it is said that the FBI used sounds of babies crying, dentist drills and a variety of other unpleasant sounds to mentally influence their opponents. The Waco compound was allegedly bombarded for long durations by these sounds via large public address systems.
Although this type of sonic assault can have a profound emotive effect on individuals, it relies heavily on the individuals particular experiences. This is where the actual physiological effects of sound are unique. Physiological changes in the body only start to occur at greater sound pressure levels. At about 120 dB discomfort begins in the ear and pain occurs when levels reach approximately 140dB.The eardrum subsequently ruptures at levels of about 160 dB. Pain becomes evident when the middle ear system is mechanically displaced beyond its normal operational limits
These acoustic effects are only apparent on the ear mechanism. The ear is a very easy structure to attack. Due to evolutionary processes the ear is particularly sensitive to midrange frequencies inherent in the human voice. Subsequently, all that is needed is an increased sound intensity at these frequencies for the threshold of pain to be readily reached. This is also related to the properties of the acoustic reflex in which a small muscle in the middle ear pulls the stirrup back from the oval window and subsequently reduces the amount of acoustic energy transmitted to the middle ear. This however only has a significant impact at frequencies lower than about 1000 Hz so that frequencies between 500 to 4000 Hz, the range at which the auditory center is most sensitive, are largely unaffected.
The acoustic effects on the body are more complex. Research has concluded that with low frequency sound in the region of 50 — 100Hz at levels of 150dB or more, intolerable sensations in the chest and thoracic region can be produced–even with the ears protected.

It all started back in 2010 in Istanbul/Turkey, where Hybrid K. and the baglama/cura player Zaffah decided to join their musical knowledge and create Komadub. One year later in 2011 Selekta Firuzaga (Dread Culture Soundsystem) joined them, and together they produced their first album called “Derinbaz”. Unfortunately the group did not last long and after the depart of Zaffah, the rest of the members decided to continue producing music under the same name, dropping beats ina digital style. The “Do Good EP” is one of the duo’s fruits of this new era.
Zion Irie (full name David Orleans), was born and grew up in UK/South London (Brixton) in an African Ghana household. After a separation from his family, he left home at the age of 14 and lived for a few years in an authentic rasta house community. Armed with hi spirituality and having a background in original soundsystem things, he taught himself to sing and write lyrics, as well as to compose tracks for the house of Zion UK. Living now in France, he has collaborated with many artists like Ackboo, Kanka, Weeding Dub and Dubsynaticx, while he shared the stage with names like Horace Andy, Brother Culture and many more.
The conscious lyrics of Zion Irie meet the oriental meditation riddims of Komadub, spreading Jah blessings to the souls of all of us. Originally the tune was planned to be included in the coming album of Komadub, which will be out later this Summer, but the sweet voice of Zion Irie and his conscious lyrics, gave the tune a dynamic of its own, which was enough reason to do a separate release and share his deep spirituality with all the family.
“Do Good” is the first work from both artists on Dubophonic and it is released as an EP with four different cuts of the title track. One vocal track, two different dub cuts by Komadub and last but definitely not least, a fourth uplifting reconstruction of the track by Alphadub (selector, operator and co-producer of Dread Culture Sound System) ina heavy steppa style, doing good for our soul, sending more and more positive vibrations with each play of the tune.
