Review of Asbestos Exposures and Practices

Sound is a mechanical wave characterized by frequency, wavelength, and amplitude, with noise defined as unwanted sound. Frequency, measured in Hertz (Hz), determines pitch, while decibels (dB or dBA) quantify sound intensity on a logarithmic scale-higher decibel levels correspond to louder sounds.

This study investigates how sound intensity varies indoors with distance and frequency, a critical concern for fields such as occupational health, safety, environmental science, acoustics, architecture, civil engineering, and noise control in venues like movie theaters and lecture halls. Understanding these dynamics is essential for managing noise pollution, which can affect human health, comfort, and productivity in both work and non-work environments.

The primary goal of this research is to analyze how noise levels change across different indoor workspaces, providing insights to inform improved environmental design and effective noise mitigation strategies.

Materials Used:
Monotone Noise Frequency Generator (capable of producing 2000 Hz, 4000 Hz, and 8000 Hz tones)
Electronic sound level meter (SLM) (for measuring decibels), Casella 63X, Digital SLM (https://casellasolutions.com), Fig 1.
Calibration device for noise SLM at 1000 Hz and 114 dBA
Measuring tape or ruler (for distance measurement), https://www.amazon.com/Measure-Mileseey-Distance-switching-Pythagorean/dp/B0863RK1KX?th=1
