Table 1: Examples of sound pressure levels in relation to hearing threshold and pain threshold (in dB SPL)The range of human ear’s audible sounds goes from 0 dB SPL (hearing threshold) to 120-140 dB SPL (pain threshold)

Table 2: Audiometric hearing thresholds of normal ears: conversion of dB SPL into dB HL (Extracted from ISO, 2003) Pure-tone audiometric thresholds are expressed in dB HL (hearing level). The differences between dB HL and dB SPL, arise from isophonic curves.
