Three core dimensions to judge the noise reduction effect of wireless narrators
When customers choose a narrator, don't blindly pursue noise reduction. The core lies in whether the three points can meet the standards. This is a reliable standard based on actual tests in the industry, which can help you avoid purchasing mistakes.
1. Signal anti-interference: Block the interference from wireless signals
The interference of wireless narrators mostly comes from wireless tour guide devices such as mobile phones and radios. Especially in crowded places like exhibition halls and business districts, the signals are chaotic, easily causing the explanation sound to freeze or have interference. Good equipment needs frequency band optimization and signal modulation to separate irrelevant signals, ensuring a clean explanation channel. This is a must-have for scenarios where multiple teams are explaining simultaneously.
2. Environmental noise filtering: Only filtering the explanation sound and noise works
For environmental noises such as factory machinery sounds, outdoor footsteps, and wind sounds, they need precise noise filtering technology. But it must not disrupt the original explanation sound. Avoid situations like "too much noise reduction, the sound becomes dull" or "noise is not filtered properly". This is particularly important for noisy scenarios like factory visits and outdoor scenic spots.
3. Original sound fidelity: Noise reduction should not lose details, and support multilingual explanations
When using multilingual explanations frequently, noise reduction technology must also take into account the voice details of different languages. Don't make the pronunciation blurry due to filtering processing. Make sure the audience can clearly grasp the key points of the explanation. This is also the key to adapting to international conferences and cross-border exhibitions.
Y3 noise reduction test: Three designs adapt to various noisy scenarios
Based on Yingmi's 18 years of narrator development experience and the scene feedback accumulated from doing foreign trade, the noise reduction design of Y3 does not resort to the superficial and artificial approach of parameter stacking. It is specifically optimized to address the common interference problems customers often encounter. Practicality and stability are both up to standard.
1. Frequency band and signal optimization: Dual protection, eliminating wireless interference
Y3 adopts a dual-frequency band adaptation design. The transmitter supports two frequency bands: 796MHz-816MHz and 860MHz-870MHz, both of which are low-interference high-frequency bands, effectively avoiding the signal interference from common wireless devices such as mobile phones and radios. It also comes with 4 adjustable channels. When multiple teams are using it simultaneously, switching channels can avoid mutual interference, especially suitable for scenarios where multiple teams are giving explanations simultaneously in museums and large exhibitions.In addition, Yingmi's core digital secondary frequency modulation anti-interference technology ensures that Y3 can accurately select the transmission signal and filter out irrelevant noise, even in outdoor open and complex signal areas, the explanation signal can remain stable without freezing or disconnection, fully meeting the needs of various scenarios.
2. Core noise reduction technology: Filter noise, preserve original sound, do both well
Y3 is equipped with Yingmi's mature SOC embedded integrated digital noise reduction technology. This technology has been refined through 18 years of industry practice and can accurately distinguish between the explanation sound and environmental noise. Through digital filtering algorithms, it filters out irrelevant noises such as machine roars and crowd noises, while maximizing the retention of the original explanation sound details. It avoids problems like too much noise reduction causing the sound to become dull or the pronunciation to be blurry. With the use of dedicated plug-in microphones or headsets, Y3 can precisely capture the voice of the presenter, further enhancing the clarity of the sound pickup, reducing the presenter's breathing sounds and clothing friction noises, while also blocking out surrounding environmental noises. Through actual testing, in factory workshops with noise intensity above 60 decibels, it can effectively filter out machine noises, allowing the audience to clearly hear the presentation content; in outdoor scenic areas, it can also block out wind sounds and footsteps, etc., as distractions.
3. Hardware Adaptation: Lightweight Design, Balancing Noise Reduction and Wearing Comfort
The receiver of Y3 adopts a non-in-the-ear ear hook design, weighing only 18g, with dimensions of 69×26×12mm. It is small and lightweight, and won't cause pressure when worn for a long time. This design not only feels comfortable to wear but also reduces the direct transmission of external environmental noises, forming a dual protection with the noise reduction technology, providing a more satisfactory listening experience.
The transmitter is equipped with a full-function LCD display, showing information such as signal strength and battery level clearly. Staff can monitor the signal status in time to avoid affecting the noise reduction effect due to signal issues. Additionally, the transmitter can last for more than 15 hours, and the receiver can last for more than 8 hours, covering scenarios such as all-day guided tours and meetings, eliminating the need for frequent charging and avoiding extra troubles.
Technical Accumulation: The Quality Foundation of Y3's Noise Reduction Effect
The noise reduction effect of the wireless guide device relies on long-term technical accumulation and quality control refinement. Yingmi has been deeply involved in the guide device industry for 18 years, with 4 automated SMT production lines, controlling the entire process from research and development to production and testing. It has also established a 7S quality control system, and each Y3 device must undergo 5 strict tests to ensure the stability and reliability of the noise reduction effect, without any batch differences.
As a national-level high-tech enterprise, Yingmi holds multiple core patents related to noise reduction, and with years of foreign trade experience, the noise reduction design of Y3 is fully adapted to various usage scenarios in different countries. It has passed EU CE and RoHS environmental certifications, and also complies with the Chinese CMA and CNAS dual testing standards. There is no need to worry about customs clearance, and no additional rectification is required. It also provides a 2-year warranty service, and with a global coverage after-sales network, customers facing noise reduction-related issues can receive professional technical support.
FAQ
Q1: Can the noise reduction effect of Y3 be adapted to strong noise scenarios such as those in factories?
A1: Absolutely. The embedded digital noise reduction technology it is equipped with can effectively filter out strong noises like the roaring of machines. Combined with the dedicated microphone, even in a noise environment of over 60 decibels, the explanation sound can remain clear, making it suitable for factory visit scenarios.
Q2: Will the noise reduction and anti-interference capabilities of Y3 be affected when multiple teams use it simultaneously?
A2: No. Y3 supports 4 adjustable channels, and with the dual high-frequency band design, when multiple teams switch channels, crosstalk can be avoided, and the anti-interference and noise reduction effects will not be affected.
Q3: Will the noise reduction processing affect the sound quality of multilingual explanations?
A3: No. It can precisely retain the details of the voice and is suitable for multilingual explanations. It will not make the pronunciation blurry, and it can solve the sound quality problems of multilingual explanations.
Q4: Has the noise reduction effect of Y3 been verified through practical use?
