[Personalization Available!] Color Triangular Scale

We accept name engraving! We would like to introduce our all-plastic colored triangular scale.

We have created an all-plastic color triangular scale to replace the conventional aluminum core color triangular scale. Since it is made entirely of plastic, it does not make any metallic sounds. We offer six colors: black, red, blue, green, yellow, and gray. *For more details, please refer to the PDF document or feel free to contact us.

Sound Divergence Ruler

Sound Divergence Ruler

Designing equipment layout, implementing preemptive measures for noise regulation laws, and addressing noise issues with neighbors!

This product is a triangular scale that allows for the identification of sound distance attenuation (geometric diffusion) in a semi-free space on a drawing. By setting the acoustic power level (PWL) of the sound source and using this product on the drawing, simple predictions of sound pressure levels can be made. * When predicting using sound pressure level (SPL), subtract 8dB from the distance attenuation (semi-free space). * In the case of 1/4 free space (when there is a wall behind the sound source), subtract 3dB from the distance attenuation. * In the case of 1/8 free space (when there are walls behind and to the side of the sound source), subtract 6dB from the distance attenuation. * It represents the distance attenuation (geometric diffusion) of omnidirectional sound. * Distance attenuation formula: PWL - 20LOG10(distance [m]) - 8 * Other environmental factors such as terrain, buildings, wind direction, and humidity cannot be predicted.
