Concert Hall Acoustics

The acoustic caliber of a live performance corridor has often posed a mysterious puzzle, specifically, what actual features of the sound box can produce enhanced sound for the listener. the writer has been probing for greater than adecade into the subjective traits most popular for musical and speech sounds. the results of his large investigations - the invention that 4 and purely 4 self sustaining parameters give a contribution successfully to stable acoustics - is summarized within the current booklet.

Management of indoor air quality

Because of alterations in way of life, humans spend extra time interior. This refers not just to the time spent at domestic and at workplace premises, but in addition in purchasing shops, sport facilities and shipping autos. Concentrations of many pollution are greater interior than they're outside. hence, the indoor atmosphere has a much bigger impression on human health and wellbeing, health and effectiveness.

Handbook of Engineering Acoustics

This acoustics guide for mechanical and architectural purposes is a translation of the German regular paintings at the topic. It not just describes the kingdom of paintings of engineering acoustics but additionally supplies useful support to engineers for fixing acoustic difficulties. It offers with the beginning, the transmission and the equipment of abatement of air-borne and structure-borne sound of alternative types, from site visitors to equipment and stream precipitated sound.

6. 4 (iii) (iv) Dehumidification 45 absorption, compression followed by cooling. The first method forms the subject matter of this section. Cooling to a temperature below the dew point is done by passing the moist air over a cooler coil or through an air washer provided with chilled water. 4 shows on a sketch of a psychrometric chart what happens when moist air is cooled and dehumidified in this fashion. Since dehumidification is the aim, some of the spray water or some part of the cooler coil must be at a temperature less than the dew point of the air entering the equipment.

3. 325 kPa, using the ideal gas laws as necessary. (b) Explain how the value would alter if the barometric pressure only were reduced. 93 kJ kg -1. 4. 7 kPa barometric pressure. Use CIBSE tables where necessary to determine saturation vapour pressure. (b) Calculate its enthalpy. 69 kJ per kg dry air. 5. (a) Distinguish between saturation vapour pressure and the vapour pressure of moist air at an unsaturated state. (b) Illustrate relative humidity by means of a p - V diagram for steam. (c) What happens if air at an unsaturated state is cooled to a temperature below its dew point?

In sensible cooling there is a further restriction: the lowest water temperature must not be so low that moisture starts to condense on the cooler coils. If such condensation does occur, through a poor choice of chilled water temperature, then the process will no longer be one of sensible cooling since dehumidification will also be taking place. 6. 3 shows the changes of state which occur, sketched upon a psychrometric chart. The essence of both processes is that the change of state must occur along a line of constant moisture content.
