Determination of room acoustic parameters for performance spaces testing method

The test method for determination of room acoustic parameters for performance spaces helps to evaluate room acoustic parameters; compare and calculate effective acoustic room design; optimize research and development of products and services to meet high performance for the acoustic environment of performance spaces and auditoriums.

Overview of the test method for determination of room acoustic parameters for performance spaces

Test method name: Acoustics – Measurement of room acoustic parameters – Part 1: Performance spaces [1]

Test method:

ISO 3382-1:2009: Acoustics – Measurement of room acoustic parameters – Part 1: Performance space [1]

Performed at: On-site at performance spaces and auditoriums.

1. Objective and test object

– Objective

This standard specifies the method for measuring reverberation time (RT60) and other acoustic parameters in performance spaces. It describes the measurement procedure, necessary equipment, scope of measurement, data evaluation methods, and how to present the test report. The standard aims to apply modern digital application methods and evaluate room acoustic parameters derived from impulse responses.

(The impulse response of a system (mechanical or electronic system) is the process of changing the state of that system after being affected by an impulse, usually modeled as a delta function. For example: tapping a drum head is the impact of an impulse on the mechanical system of the drum, and the system's response is the decaying vibration of the drum head, emitting sound. Or an electronic system with an input and an output, receiving a voltage pulse as the input signal, the output signal at this time is precisely the impulse response of the electronic system.)

– Object:

Performance spaces, auditoriums.

2. Experimental procedure

Execution steps:

• Prepare all necessary equipment, microphones, and test samples.
• Determine measurement locations.
• Perform sample measurements:

+ Interrupted noise method

+ Integrated impulse response method

• Process and report results.

Role – importance of the test method for determination of room acoustic parameters for performance spaces

The test method for determination of room acoustic parameters for performance spaces performed by the DASM Institute helps meet practical needs such as:

• Enterprises need to control quality during production, optimize research and development of products and services to meet high performance for the acoustic environment of performance spaces and auditoriums.
• Customers need to obtain certificates and test results to enhance the value and brand of works and projects in a convenient, transparent, and compliant manner.
• Having a basis and standards to evaluate room acoustic parameters; comparing and calculating effective acoustic room design.

Besides, in case the object does not meet the standards, DASM will carry out consulting and designing solutions for shapes, shapes, structures, and materials used to adjust the design in a streamlined, effective, and cost-saving manner.

If previously you had some concerns and worries and had to spend a lot of fees for similar activities abroad, now you just need to contact DASM. The entire remaining process will be proactively implemented by us as a complete package in the fastest time to complete the customer experience about us: DASM provides acoustic consulting services with truly superior quality, the most competitive prices in the industry along with thoughtful and dedicated customer care policies.
