Descripción : The present research pretends to evaluate the effect that occurs in the water when it is exposed to a sound produced by Tibetan bowls. For this, it was necessary to synthesize in the laboratory a water sample with a significant concentration of: potential Hydrogen (pH), Total Hardness (TH), Calcium, Nitrite, Nitrate, Ammonium and COD (Chemical Oxygen Demand). The concentration of these parameters in the water sample was obtained in the laboratory by a spectrophotometer. In addition, concentration values were measured for each water sample obtained at the different time intervals, while the experiment was in progress. A prototype was also designed and implemented, which allowed the fluid to be stimulated only by acoustic energy and not by the mechanical energy present in the membrane of the loudspeaker. Recordings of Tibetan bowls were used, so it was necessary to design a simple electroacoustic chain for the reproduction of these audio samples. Therefore, a statistical analysis was developed that allowed comparing the data of exposure time and electrical power with the percentage of reduction of the chemical concentrations present in the water samples. For this, trend equations were proposed for each parameter measured as a function of time, to obtain values outside those already established in the methodology. After obtaining the results and analyzing them, a variation was observed in almost all the parameters measured. In many cases these changes referred to a reduction of the initial level present in the water sample. This decrease in measurements occurred mainly in the first 10 minutes of exposure. On the other hand, the power could not be modeled in an equation, due to the lack of records taken. However, the collected information allowed to identify that, for certain parameters, a higher level of energy is necessary if it is desired to obtain a greater reduction of concentration
