Frequent questions about USB Noise Meter (Pro Edition)


Wie groß ist der Frequenzbereich des USB Noise Meter (Pro Edition) von SPL Lab?

The frequency range of the USB Noise Meter (Pro Edition) extends from 10 Hz to 20,000 Hz. This allows for the measurement of a wide spectrum of acoustic signals, from extremely low frequencies to high tones within the audible range. This broad coverage is particularly valuable for applications in spectral analysis, as it ensures a comprehensive measurement of all relevant frequencies. Especially for audio experts or engineers involved in the evaluation of audio systems, this wide frequency range provides an excellent foundation for conducting precise and detailed analyses.

Welche Funktion hat die integrierte 16-Bit-ADC-Einheit im USB Noise Meter?

The 16-bit ADC unit in the USB Noise Meter from SPL Lab converts the analog signals captured by the microphone into digital signals. This is crucial for precise signal digitization and allows the converted signals to be transmitted directly to a computer via the mini-USB port. This 16-bit resolution ensures high accuracy in conversion, which is essential for differentiated spectral analyses and precise measurement of sound pressure levels. This is particularly advantageous when one wants to perform accurate audio measurements in different environments.

Was sind die Vorteile des Amplitudenbereichs von 80 bis 150 dB beim USB Noise Meter?

An amplitude range of 80 to 150 dB on the USB Noise Meter means that the device can accurately capture sounds from extremely quiet to very loud. This range is important for various applications, from measuring background noise in quiet rooms to capturing loud machinery in industrial environments. High levels can be measured without distortion, which is crucial for precise audio analysis. This ability to cover such a range ensures that the USB Noise Meter can be reliably used in many acoustic scenarios.

Wie beeinflusst der Materialeinsatz aus eloxiertem Aluminium die Leistung des USB Noise Meter?

The housing made of anodized aluminum in the USB Noise Meter not only provides protection but also optimizes the acoustic performance of the microphone. Aluminum minimizes resonances and overtones that could be caused by external influences, thus ensuring an acoustically optimized environment for precise signal capture. Additionally, the robust material offers protection against physical damage. Especially for users who measure in various environments, the durable housing is essential as it maintains the functionality of the measuring device even under demanding conditions.

Welche Softwarefunktionen bietet das USB Noise Meter für Spektralanalyse und SPL-Messungen?

The included software of the USB Noise Meter from SPL Lab provides comprehensive tools for spectral analysis and the measurement of absolute sound pressure levels (SPL). This allows for detailed examination and analysis of signals regarding their frequency components. In addition to comprehensive frequency response analysis, harmonic distortions and signal waveforms can also be captured. The software also enables the adjustment of crossovers and filters, which is crucial for the optimal tuning of audio systems. For audio technicians, this offers a powerful tool for all relevant acoustic measurement techniques.

Wie wird der USB Noise Meter im Auto für die AFC-Messung installiert?

The USB Noise Meter can be easily installed in the car to measure the AFC (Amplitude Frequency Response). Its compact design and anodized aluminum housing make it ideal for use in tight spaces. The device can be securely positioned on a stand to ensure stable measurement conditions. Users can easily connect the measuring device to a laptop or another computer for control via a mini-USB interface. The AFC measurement can then be conveniently performed using the supplied software to optimally tune the audio system and obtain precise acoustic measurements.

Welche dynamischen Möglichkeiten bietet das USB Noise Meter von SPL Lab?

The wide dynamic range of 70 dB of the USB Noise Meter from SPL Lab enhances its ability to distinguish between quiet and loud acoustic signals without clipping or distortion. This is essential for applications where both subtle and accentuated sound ranges need to be captured. For example, quiet ambient noises and loud machinery can be accurately measured with the same device. This dynamic flexibility facilitates complete spectral coverage in applications that involve the entire audible range, including detailed audio profile organization in car and home theater installations.

Welche Rolle spielt der Niederfrequenzverstärker im USB Noise Meter?

The integrated low-frequency amplifier in the USB Noise Meter is of particular importance as it amplifies signals in the lower frequency range, thus ensuring a more precise measurement of low-frequency noise. Especially when measuring audio systems or in industrial areas where low-frequency vibrations play a role, this amplifier allows for more accurate differentiation and analysis. In conjunction with the 16-bit ADC unit and the acoustically optimized housing design, the device offers comprehensive capabilities for precise sound evaluation across the entire frequency spectrum.

Wie wird das USB Noise Meter an den PC angeschlossen?

Connecting the USB Noise Meter to a computer is straightforward via the mini-USB port. The included USB cable serves as the interface, establishing a fast and reliable connection. This connection allows the measurement results to be transferred directly into the Spl-Lab measurement center software for Windows and Android. As a result, users have the ability to access the data in real-time and conduct comprehensive analyses. This seamless connection between hardware and software significantly simplifies routine use in various acoustic applications.

Welche akustischen Vorteile bieten die speziellen Kerben im Gehäuse des USB Noise Meter?

The special notches in the housing of the USB Noise Meter are designed to promote a smoother directional characteristic of the microphone. This structure minimizes unwanted sound shadows and reflections, which is particularly advantageous in demanding acoustic environments. As a result, the overall recording accuracy is improved by focusing on the intended sound field and reducing distortions. This acoustic fine-tuning ensures exceptional sound fidelity and is appreciated by audio professionals and engineers who need to perform clear and accurate measurements in various application scenarios.
