Next-Lab SPL Sensor by SPL Lab

The SPL Lab Next-Lab SPL sound pressure sensor is designed for use with data analysis units such as Next-LCD and Next-USB. The device features an internal ADC. The signal is digitized in the sensor and transmitted in digital form via the Lab bus. This prevents distortion and noise interference of the measured signal during transmission. The signal can be transmitted via a cable with a distance of up to 10 meters. The Next-Lab SPL sensor has an extended amplitude range and a noise reduction system that allows measurements with an accuracy of up to 0.1 dB. Each copy of the device is thoroughly tested and calibrated. The device is designed as a monoblock and consists of a high-frequency semiconductor sensor, ADC module, and Lab bus interface. The device has a Lab bus port for data transmission. On the back, there are vacuum suction cups for attaching the device to smooth surfaces such as glass. The housing of the device is made of shock-resistant plastic.

Frequent questions about Next-Lab SPL Sensor


Wie funktioniert der interne ADC des Next-Lab SPL Sensors?

The Next-Lab SPL Sensor from SPL Lab uses an integrated analog-to-digital converter (ADC) to digitize the input signal. The internal ADC operates with a resolution of 16 bits, ensuring precise conversion of the analog input signal into a digital format. This digitization allows for lossless transmission of measurement data over the Lab-Bus digital bus. This is particularly advantageous in the frequency range of 10 to 120 Hz or 10 to 20,000 Hz depending on the model, as the highest precision of up to 0.1 dB can be guaranteed. This implementation reduces signal line influences and prevents possible distortions during the measurement process.

Welche Frequenzbereiche deckt der Next-Lab SPL Sensor ab?

The Next-Lab SPL Sensor offers a different frequency range for capturing audio signals depending on the model. The basic version covers a frequency range of 10 to 120 Hz, particularly suitable for low-frequency applications such as subwoofer tests. The Wide Band Edition, on the other hand, dramatically expands this range to 10 to 20,000 Hz, allowing for comprehensive use across a wide range of frequencies, including application in complete audio system analyses. These bandwidths enable diverse usage, from analyzing low frequencies to comprehensive acoustic tests across a wide spectrum.

Wie wird der Next-Lab SPL Sensor montiert?

The installation of the Next-Lab SPL sensor is effortless thanks to the vacuum suction cups attached to the back. These allow the sensor to be securely mounted on smooth surfaces like glass. The robust, shock-resistant plastic of the housing ensures a long lifespan and reliability even with intensive use. The sensor is designed as a compact monoblock, which simplifies handling while ensuring precise positioning for optimal data acquisition. The mounting method also promotes flexibility in placement, making it ideal for different measurement configurations.

Welche Genauigkeit bietet der Next-Lab SPL Sensor bei Messungen?

The Next-Lab SPL Sensor is characterized by an impressive measurement accuracy of up to 0.1 dB. This high precision is made possible by the use of an internal 16-bit ADC and careful calibration according to TERM-LAB standards. By digitizing the signal before transmission over the lab bus, accuracy is maintained even with signal lines of up to 10 meters. Customers who require precise and reliable sound pressure measurements – whether for use in car audio competitions or for acoustic fine-tuning – will appreciate the advantage of these precise measurements.

Welche Amplituden kann der Next-Lab SPL Sensor messen?

Depending on the model, the Next-Lab SPL sensor can measure different amplitudes. The basic version is designed for amplitude measurements between 110 dB and 185 dB, covering typical applications in dynamic bass applications. Meanwhile, the Wide Band Edition covers a range from 100 dB to 182 dB, allowing for more comprehensive testing even at lower volumes. This is particularly crucial for users involved in SPL measurements at car audio competitions or acoustic system tests, especially when evaluating systems with variable volume.

Welche Verbindungsmöglichkeiten bietet der Next-Lab SPL Sensor?

The Next-Lab SPL sensor is equipped with a lab bus digital bus, through which the digitized signal can be transmitted losslessly and precisely. This connection ensures that the signal can be transported over distances of up to 10 meters without compromising signal quality. This technology achieves a higher measurement accuracy than is possible with analog data transmissions. The connection and integration into existing measurement systems that use Next-LCD or Next-USB is straightforward, supporting seamless integration into existing analysis environments.

Ist der Next-Lab SPL Sensor mit bestimmten Automarken kompatibel?

The Next-Lab SPL sensor itself is independent of specific car brands, as no direct connection to the vehicle's electronic systems is required. Important for compatibility is primarily the space required for installation in the vehicle. The sensor needs a smooth surface for the vacuum suction cup attachment, as is found on the windows of vehicles. It is important to ensure that there is sufficient space in the vehicle to allow for efficient operation during the measurement process – especially important for measurements in tight vehicle cabins or in competition vehicles.

Welche Aspekte der akustischen Systeme können mit dem Next-Lab SPL Sensor analysiert werden?

With the Next-Lab SPL Sensor, many aspects of acoustic systems can be analyzed in detail. In addition to general sound pressure level measurement, the sensor supports the spectral analysis of a signal, the measurement of harmonic distortions in low-frequency signals, as well as the adjustment of components such as subwoofers. This is particularly interesting for users who want to optimally set up and measure acoustic systems, for example, in preparation for car audio competitions like IASCA or dB Drag. Improved system settings often contribute to optimizing acoustics and are popular among both competitive and private audio enthusiasts.

Wie genau werden Geräusche mit dem Next-Lab SPL Sensor reduziert?

The extended amplitude range of the Next-Lab SPL sensor and its noise reduction system play a key role here. By integrating the digital lab bus, the signal is generated in digital form already in the sensor. This prevents signal distortion during transmission, significantly reducing the burden of electronic interference. The system is designed to minimize noise, ensuring that measurements can be conducted with a precision of up to 0.1 dB. This is particularly important for accurate analyses and competitive applications.

Kann der Next-Lab SPL Sensor für die Vorbereitung auf Caraudio-Wettbewerbe genutzt werden?

Yes, the Next-Lab SPL Sensor is perfectly suited for preparation for car audio competitions. With its high measurement accuracy of up to 0.1 dB and the ability to measure amplitudes from 110 to 185 dB, it is ideal for fine-tuning audio systems. Competitions like AMT, EMMA, or BassRace require precise measurements and adjustments that the sensor can support. The digital lab bus data channel ensures that measurements remain accurate even over longer distances in the vehicle, which is relevant in complex sound setups.
