INTEREST in combustion noise in the domestic context has been increasing in recent years because of the more widespread adoption of central heating and the advent of natural gas. Much of the previous work on open turbulent flames has been concentrated on gas/air mixtures1–4whereas Roberts and Leven-thall5 consider the noise of domestic natural gas burners. Most of the work concerned with burning oil sprays has been performed on enclosed flames, with the exception of that of Headly et al.6 and Palmer7.
