Noise-Cancelling PCB Modules vs Noise-Cancelling Speakers: A Complete Guide To Choosing Your Ideal Audio Solution

Are you struggling to hear clear speech through background noise? At bhi Ltd, we offer a range of noise cancelling products that reduce background noise and interference to make speech more intelligible. Two of our main solutions include noise cancelling PCB modules and noise cancelling speakers. Each option uses our excellent DSP noise cancelling, but suits different situations and user needs.

This guide compares these technologies to help you determine which solution matches your requirements. Got any questions? Speak to our team today to discuss your requirements.

Understanding our DSP noise cancellation technology

Our unique Digital Signal Processing (DSP) noise cancellation technology identifies and removes unwanted background noise while preserving speech signals.

The DSP works in real-time to separate speech from background noise. Unlike simple filters, it adaptively processes audio, keeping speech clear and reducing unwanted noise.

The fundamental difference between our modules and speakers isn't the core technology but rather how and where it's implemented in your audio chain. Both use the same advanced DSP algorithms but package them differently to suit various installation preferences and requirements.

Key features of bhi PCB DSP modules

bhi's PCB DSP modules allow you to integrate our unique DSP noise cancellation directly into existing equipment. There are PCB modules for both low-level audio and amplified audio signals. Both provide exceptional noise reduction capabilities in small form factors.

These modules include adjustable filter levels, allowing users to select the appropriate noise cancellation intensity. The modules offer 8 different filter settings, ranging from gentle noise reduction to higher levels of filtering for severely noisy conditions. The low level audio PCB modules are more suited to retrofitting in older radios and receivers or into new designs, whereas the amplified PCB modules are more suited to retrofitting inside extension speakers.

Installation and electronic knowledge are required when choosing PCB modules. While we provide detailed installation guides for popular radio models, some technical knowledge is necessary. Users must identify appropriate connection points and may need to modify existing equipment.

Key features of bhi speakers

bhi DSP noise-cancelling amplified speakers deliver the same advanced DSP noise cancelling technology in convenient standalone units. These speakers connect to your existing audio output and provide immediate noise reduction without internal modifications to your equipment.

The speaker range includes the compact NES10-2 MK4 and the larger DESKTOP MKII. All models incorporate high-quality speaker drivers paired with our noise cancellation technology in acoustically designed enclosures.

These speakers feature easy-to-use controls for simple operation, including power on/off, filter level adjustment, and volume control. They both offer various input and output connections, allowing them to integrate into audio chains while providing pass-through capabilities for headphones or additional speakers.

The primary benefit of noise-cancelling speakers is their plug-and-play nature. Users simply connect the speaker to their audio source, connect power, and immediately gain noise cancellation benefits. This approach requires no technical expertise or equipment modifications.

Audio performance comparison

Both PCB modules and noise-cancelling speakers utilise identical DSP algorithms, resulting in similar noise reduction performance. However, implementation differences create distinct audio characteristics worth considering.

Modules maintain your existing audio chain's characteristics while adding noise cancellation. This approach preserves the familiar sound signature of your equipment while reducing unwanted noise. For users who appreciate their current speaker's sound quality but need noise reduction, PCB modules offer targeted enhancement without changing overall audio character.

Noise-cancelling speakers provide a complete standalone solution, including amplification, processing, and sound reproduction. This integrated approach ensures all components work together optimally, but introduces a different sound character compared to your existing speakers. Some users prefer this "fresh start" approach, while others may prefer maintaining their current sound signature.

Space and portability considerations

Physical space requirements and mobility needs significantly influence the choice between PCB modules and noise-cancelling speakers.

Modules excel in space-constrained environments. Once installed, they add noise cancellation without increasing your equipment footprint. This internal integration proves ideal for fixed installations with limited desk or shelf space. Mobile operations with size and weight restrictions also benefit from this space-efficient approach.

Noise-cancelling speakers occupy additional physical space. The NES10-2 MK4 measures approximately 110 x 65 x 55mm, while the DESKTOP MKII measures 200 x 150 x 160mm and requires more substantial desk space.

Decision Guide: Selecting the right solution for your needs

Consider the following when trying to find the right noise cancelling product for your needs:

Technical expertise

If you possess electronics knowledge and installation skills, modules provide cost-effective solutions with clean integration. For those without a technical background or who prefer avoiding equipment modifications, speakers offer accessible noise cancellation without installation challenges.

Usage

If you use multiple radios or audio sources, speakers provide adaptable solutions that can be plugged into a range of different equipment. Modules can only be installed in one radio or speaker, so they are perfect for those who have a dedicated setup with only one audio source needing noise cancelling.

Space

Operators with limited desk space may prefer modules that add functionality without increasing equipment footprint. Those with adequate space might appreciate the standalone nature and comprehensive controls of speaker solutions.

Adaptability

If you frequently change equipment or operate in varied environments, speakers provide flexibility to use with different audio sources. For permanent installations with stable equipment configurations, modules offer integrated solutions that become part of your system.
