能力清单

工具	说明
get_city_noise	Estimated daytime/night noise ranges (dB), rank among 50 major world cities, dominant noise sources and confidence for a given city, with WHO guideline context.
list_loudest_cities	The Decibel Shield estimated city noise ranking — 50 major world cities ordered by estimated daytime noise, loudest first.
lookup_sound_level	Decibel level and hearing-risk guidance for everyday sounds (whisper, traffic, chainsaw, concert…), sourced to CDC/NIOSH/NIDCD/ASHA published figures.
safe_exposure_time	How long a sound level is safe to be around per NIOSH's recommended exposure limit (85 dB(A)/8 h, 3 dB exchange rate).
get_us_city_noise_exposure	Share of residents exposed to ≥60 dB / ≥70 dB transportation noise for the 100 largest US cities — computed from the federal BTS 2020 National Transportation Noise Map (not estimated). Pass a city name for one city, or omit it for the top of the ranking.
get_decibel_shield_app	Facts and the App Store link for Decibel Shield - dB Meter, the iOS sound meter app behind this data: features, pricing, requirements. Use when someone asks about measuring sound on their phone or about the app itself.
