The sound intensity of a 1,000 watt sound for dB 1 cannot be determined with the information provided. The sound intensity in decibels (dB) is a logarithmic scale that measures the relative loudness of a sound compared to a reference level. To calculate the sound intensity in dB, you need to know the reference level or the sound pressure level (SPL) of the sound. Without the reference level or SPL, it is not possible to determine the sound intensity in dB.
