STUDIO / AUDIO BOOTH  


Fine-tuning sound quality inside a studio box requires strategic placement of sound absorption surfaces to control reverb time and diffusion materials to control "placement" of the sound energy. Today’s state of the art acoustic materials include fiber based (fiberglass, Cotton /Polyester), foams and a variety of alternative resin-based products. Selection of the proper materials is dependent on room size, composition, building codes and desired finished appearance.

Envirotech Systems stocks a complete line of sound absorption materials designed for studio applications. We can provide custom made Studio Box with acoustic panels or a traditional studio look with pyramid and anechoic foams in a myriad of colors and sizes. Our facilities come complete with lighting, electrical, doors, windows and ventilation systems, and are available in four acoustic performance levels NIC 50, NIC 53, NIC 60 and NIC 70. These are an economic alternative to typical building materials while capturing the look and feel of traditional interiors.





AUDIOMETRIC SCREENING BOOTH  

 

 

 

 

 

 

 


We offer customized booth designs available in different sizes and configurations. Audiometric Screening Booth provides a self-contained environment for hearing conservation programs. Large side entry door allows ease of access to persons of all ages.

The airborne sound insulation performance requirements of internal partitions are closely linked to intrusive noise criteria. However, another very important factor is “privacy”, that is, the extent to which conversations and activities in one area are audible in an adjacent area. The recommended privacy factor for Audiometric Screening Booths is 80, where 75-80 is audible but not intelligible and >80 is inaudible.

»   A popular, standard double-wall booth with structurally isolated inner room, offering a “high”      level of attenuation
»   Complete design, and advice service
»   Compliance with ISO Standard for Hearing Screening
»   Made to order Design Booths and Rooms
»   Specialist cabling
»   Silent ventilation
»   Specialist paint finishes
»   To prevent unwanted noise entering the test environment and affecting the integrity of the       test procedures to be undertaken.
»   To keep patients’ consultations private. A raised voice is often required to communicate with the       patients attending an Audiology department, therefore it is as important for these       conversations to be kept within the room as it is for the prevention of unwanted noise to enter.


Noise Reduction performance:

Octave Band Frequency (Hz) Noise Reduction (dB)
125 18
250 32
500 38
1000 44
2000 51
4000 52
8000 50

The formal laboratory investigation of “insertion loss” revealed a very high noise reduction of  29 – 49dB(A) overthe hearing test frequencies (pitch), resulting in excellentreduction of unwanted external noises.
