JIS C 1515 Octave Band Filter Testing for NVH Instrumentation
The JIS C 1515 standard, titled “Octave Band Filters,” is a critical document in the automotive testing industry. It outlines specifications and procedures for creating octave band filters used in noise, vibration & harshness (NVH) instrumentation systems. This service ensures that NVH instruments can accurately measure sound pressure levels across specific frequency bands.
Accurate measurement of these parameters is essential for understanding vehicle acoustics during development stages. By applying JIS C 1515 standards, manufacturers ensure their products meet rigorous international quality control benchmarks. The test involves precise calibration and characterization of octave band filters which are then used in conjunction with sound level meters to gather data.
The process begins by selecting appropriate filter types based on the frequency range required for the specific application. For instance, if an automotive manufacturer wishes to analyze engine noise at various stages of product development, they would choose filters that cover those relevant frequencies. After selection, calibration is performed using traceable standards ensuring repeatability and consistency.
Once calibrated, these filters are incorporated into NVH measurement systems. During testing, the system captures sound signals within each designated frequency band. These captured data points form the basis for evaluating vehicle acoustics performance against set criteria. Compliance with JIS C 1515 ensures that all measurements adhere to internationally recognized standards, providing confidence in product reliability.
Compliance with this standard is not just about meeting regulatory requirements but also enhancing customer satisfaction through superior product quality. Automotive companies can leverage accurate NVH testing results from Eurolab's services to improve design iterations and ultimately deliver quieter, more comfortable vehicles for end-users.
| Filter Type | Frequency Range (Hz) | Description |
|---|---|---|
| A-Weighted | 20 Hz - 16 kHz | Primarily used for sound levels measured in the vicinity of noise sources. |
| C-Weighted | 20 Hz - 1 kHz | Suitable when there is a need to emphasize low-frequency components over high frequencies. |
