Answer 1

The townspeople should be concerned because the increase to 100 dB exceeds the recommended exposure limit of 85 dB for 8-hour periods without hearing protection, which could potentially lead to hearing damage.

Step-by-step explanation:

The community's concern regarding the proposal to bring train service to the downtown area from the outskirts can be addressed by understanding sound levels and their impact on human health. The sound intensity level is currently 70 dB in the downtown area. If the mayor's assurance stands, and the difference in sound intensity level will be 30 dB, then the resultant sound intensity level would be 100 dB, which is well above the 85 dB threshold recommended by various government agencies and health associations for 8-hour daily exposures without hearing protection.

When it comes to experiencing music from speakers without noticing significant volume fluctuations due to constructive and destructive interference, this can be attributed to the average range of wavelengths produced by the music and the distances involved, typically smoothing out such interference patterns to the average listener moving around the speakers.
