Bacterial Acoustic: Investigating the Impact of White Noise on the Growth of E. Coli

Microbiology

Grade:
11
Teacher:
Alfred Santos

This research project investigates the influence of white noise frequencies on the growth of E. coli bacteria within the audible range of 14,500 – 15,000 Hertz (Hz). White noise, characterized by uniform intensity across all frequencies between 20-20,000 Hz, is known to mask disruptive environmental sounds. However, its potential impact on biological systems, particularly bacterial growth, remains an underexplored area.
