Measuring the intensity of a sound wave without any equipment can be challenging, as it typically requires specialized instruments to obtain accurate measurements. However, you can make rough estimations or comparisons using your senses and some basic knowledge.
Relative Comparison: You can compare the intensity of different sound sources by listening to them and assessing which one seems louder. While this method is subjective and lacks precision, it can give you a general idea of the relative intensity of the sound sources.
Distance Effect: In general, sound intensity decreases as you move away from the source. You can compare the loudness of a sound at different distances to get an indication of the relative intensity. As you move farther from the sound source, the intensity will decrease.
Sound Pressure Level (SPL) Estimation: Sound pressure level is a measure of sound intensity. While you cannot measure it precisely without equipment, you can estimate whether a sound is relatively high or low intensity based on its perceived loudness. Louder sounds tend to have higher intensities, while quieter sounds have lower intensities.
It's important to note that these methods provide only subjective estimations and are not suitable for obtaining accurate quantitative measurements of sound intensity. For precise measurements, specialized equipment like sound level meters are required.
