The advantages of using Leq in measurements include: Leq​ is a globally recognized parameter that summarizes the fluctuating levels of noise over a particular period into an average value. This makes it a convenient tool for communicating the overall noise exposure or environment The A-weighted Leq emphasizes frequencies to which the human ear is most sensitive and de-emphasizes those frequencies where our hearing is less sensitive. This makes LAeq​ particularly relevant for human exposure as it represents the noise in a way that aligns with our perceptual response. LAeq​ provides an average of the entire audible frequency range, which can be crucial for a holistic understanding of the sound environment. Leq can be frequency-weighted (e.g., A, C, or Z weightings) to provide insights into specific frequency contributions, including the influence of low frequencies. Leq integrates varying sound levels over time, providing a consistent representation as a single dB value, which depicts the equivalent continuous sound exposure, Leq serves as a foundational metric from which various other acoustic indicators, like LEX,8h for occupational noise or Rating Level for environmental noise, can be derived. Leq can be represented as a frequency spectrum in 1/1 or 1/3 octaves to assess the annoyance accurately.
