Decibel (dB) levels measure sound intensity primarily for human perception, but animals often have more acute hearing, detecting frequencies and intensities humans cannot. The CIPS L3M6 module notes that while noise regulations (e.g., 85 dB workplace limits) target human health, animals (e.g., dogs hearing up to 45 kHz vs. humans at 20 kHz) are more vulnerable to noise pollution from supply chain activities like transport. This makes the statement true, as decibel standards are human-centric, though environmental impacts on wildlife are also considered in LO2’s broader sustainability context.
