Tone prominence ratio is finding increasing use as a tool for product sound design. ECMA‐74 Annex D offers a procedure for calculating tone prominence ratio and qualifying tone audibility. However, there are significant potential sources of error when utilizing the ECMA‐74 procedure. These include possible misidentification of tone frequency, and ambiguities about what constitutes tone audibility. Misidentification of tone frequency can occur when closely spaced tones exist in the spectrum; whereas, other errors may result from individual subjective assessment of tone audibility. The existing ECMA method does not specify how to identify the primary tone frequency when such ambiguities exist. Real‐world examples of potential error sources are presented along with proposed solutions. An unambiguous peak prominence ratio value reporting system is presented along with data to support its improved relevance in terms of hearing perception and subjective annoyance. |
