Abstract

The increasing use of wireless devices, coupled with the rise in environmental noise, creates challenges for maintaining the quality of radio signals. This research investigates the environmental noise levels in Cross River State, Nigeria, and their effects on the signal strength of FAD FM 93.1, a local radio station. The research employs a comprehensive measurement procedure using a noise level meter and a CATV signal strength meter in six selected local government areas. Data collection spans four months, covering both rainy and dry seasons. The obtained results were evaluated based on study locations, times of day, noise level and signal strength. The findings of the study were analyzed to create a visual representation using MATLAB software. The signal strength transmitted by FAD FM during the study period was measured at 76.2 dB. Results reveal an inverse correlation between environmental noise and FAD FM signal strength, indicating that increased noise leads to decreased signal quality. Simulated results illustrate the impact of noise fluctuations on signal strength throughout the day, emphasizing peak traffic and industrial hours as critical periods. The study attributes poor signal performance to high noise levels, suggesting practical advice for noise reduction in the study locations. Additionally, a model is proposed to determine the efficiency of the signal strength received in these selected areas. In conclusion, the findings highlight the significance of addressing environmental noise to enhance radio signal reception. Recommendations include targeted noise reduction strategies, optimization of signal reception, and continuous monitoring. This work contributes valuable insights for radio signal analysis and offers a foundation for further research in noise reduction efficiency and signal quality enhancement.
