WebSensible heat (S.H) is the heat which increases or decreases the temperature of the body. Latent heat (L.H) is the heat which is absorbed or released during phase change; Total heat (T.H) is the sum of sensible heat and latent heat. T.H = S.H + L.H. Sensible heat factor (S.H.F) The sensible heat factor is the ratio of sensible heat to total heat. nuh audiology department
