Rion Unveils the Innovative NX-43RV Reverberation Time Program

Rion Inc., headquartered in Kunitachi City, Tokyo, has recently launched the NX-43RV program, enhancing its sound level meters with the capability to measure and evaluate reverberation time directly on-site. This is a significant leap, allowing users to bypass the need for a separate impulse sound source and offer enhanced ease of use in various indoor locations.

What is Reverberation Time and Its Importance?

Reverberation time is a critical criterion for assessing speech intelligibility in spaces such as conference rooms, classrooms, and auditoriums. It plays a vital role during the final stages of construction or renovation when verifying the acoustic properties of a building. With growing demands for efficient on-site measurements and the challenges posed by equipment restrictions, the new program NX-43RV was developed to meet these needs comprehensively.

Key Features of NX-43RV

1. Dual Measurement Methods: The NX-43RV supports two measurement methods for reverberation time, in accordance with ISO 3382-2: the traditional noise interruption method and the new impulse response squared integration method. The latter allows for measuring reverberation time without the need for speakers, utilizing stable impulsive sounds instead.

2. Streamlined On-Site Analysis: This program enables measurement and calculation of reverberation time (T20, T30, T15, EDT) using a single sound level meter, eliminating the previously-required external data analysis on computers. Users can visualize their measurements in graphical or numerical formats across frequency bands, simplifying real-time assessments.

3. Real-Time Data Validation: Adhering to ISO standards, users can confirm the reliability of their measurements on-site. If a measurement surpasses preset thresholds, the device immediately highlights this, making it easier to judge whether retesting is necessary. Additionally, users can overlay background noise data with their measurements for straightforward analysis.

4. Enhanced Measurement Efficiency: The NX-43RV features an automatic level trigger function, allowing for up to ten continuous measurements for increased precision and efficiency. Users can also manually exclude unwanted data from their averages, with a capacity to store up to 40 results in one data file.

5. Simultaneous Recording of Waveforms: By combining NX-43RV with the waveform recording program NX-43WR, users can capture sound pressure waveforms alongside reverberation time measurements, facilitating deeper post-analysis with dedicated software.

Complementary Products for Enhanced Functionality

For those utilizing the noise interruption method, Rion offers a battery-powered amplifier, Nor282, and an omnidirectional speaker, Nor283, which can be seamlessly integrated with the NX-43RV for a comprehensive measurement system.

Ideal Applications

• - Assessing the acoustic characteristics of indoor environments like offices, auditoriums, and classrooms.
• - Evaluating acoustic performance during construction or after renovations.
• - Testing the effectiveness of sound absorption materials implemented in spaces.
• - Conducting measurements in construction sites where power supply may be limited.

The NX-43RV program represents a significant advancement in convenient and efficient sound measurement technology. For further details about the NX-43RV reverberation time program, you can visit the official Rion website.
