Bioacoustic Therapy is a sound healing technique in alternative medicine that involves the analysis of soundwaves produced during vocalization combined with presentation of low frequency analog sound to promote healing. [1] The word "acoustic" is derived from the ancient Greek word ακουστός, meaning able to be heard (Woodhouse, 1910, 392). The science of acoustics studies the production, control, transmission, reception, and effects of sound wave vibrations.[2] Bioacoustics investigates both biology and acoustics, specifically as these relate to animals, including humans, with emphasis on evolution. As a science, bioacoustics is concerned with the production of sound and its effects on living systems. In animals, the most effective type of communication for most species is sound.[3]

Within the broad category of sound therapy, the use of sound vibrations and frequency for therapeutic effect,[4] bioacoustic therapy is a subcategory. Other subcategories of sound therapy[5] include music therapy – the use of rhythm, melody, and harmony through singing, dance and instruments to achieve relaxation and creative states of awareness,[6] psychoacoustic therapy – the study and use of sound perception[7], and Hemi-Sync – the therapeutic use of binaural beats in audio patterns[8]
Bioacoustic therapy is distinguished from other sound therapy subcategories by the use of human voice analysis as a representation of the person’s state of health. Voice analysis detects frequencies the person emits, known as a “signature sound”, which represents vibrational energies of the body and its functions[4]. Sound frequencies emitted by all animals vary with their state of physical and emotional health. Physical functioning, genetic and environmental factors all influence these frequencies which can be detected with bioacoustic equipment. Once the altered vibrations are detected with voice analysis, the body’s energy field is harmonized by listening to one’s personalized corrected sound frequencies. These frequencies support health and enable healing.[4]
