Yet, in their density, robustness and absorbency, semolina-dusted English muffins are quite clearly the most practical base for all that hollandaise and (unless something has gone disastrously wrong), egg yolk.
Painstaking adjustments are made by careful attention to the choice of microphones, by the arrangement and sound absorbency of walls and furniture on the set, and by the exact positioning of the actors.
Making fabrics softer and sometimes also increasing absorbency involves the addition of such agents as dextrin, glycerin, sulfonated oils, sulfated tallow, and sulfated alcohols.
They may have added ingredients to retard rancidity and to encourage moisture absorbency and retention.
The best single measure of acoustic performance for auditoriums is the reverberation time, which is directly proportional to the volume of the hall and inversely proportional to the amount of sound absorbency within it, including wall and ceiling surfaces and the audience itself.
Texturizing processes make yarns more opaque, improve appearance and texture, and increase warmth and absorbency.
Bulking creates air spaces in the yarns, imparting absorbency and improving ventilation.
People are excellent sound absorbers, and thus the audience has a distinct impact on auditorium acoustics; to keep this effect constant with varying audience size, auditorium seats are usually upholstered to serve as surrogate spectators of the same sound absorbency.
