Frequently Asked Questions About General Soundproofing

What is soundproofing?
Soundproofing is the process of reducing or blocking sound transmission between spaces or from external sources, using materials and techniques to absorb, dampen, or isolate noise for quieter environments.

What are soundproofing materials?
Soundproofing materials reduce or block noise by absorbing, damping, or isolating sound waves. They address airborne noise (e.g., traffic, machinery) and structure-borne noise (e.g., vibrations), creating quieter environments in industrial, residential, or automotive settings.

What types of soundproofing materials does Sontech offer?
Sontech provides Acustimet®, a microperforated panel for absorbing airborne noise, and VIBRALON 25 SB, a viscoelastic material for damping structure-borne vibrations. Both are patented, lightweight, and eco-friendly, suitable for diverse applications.

How does Acustimet® work as a soundproofing material?
Acustimet® uses microperforated panels to trap airborne sound waves, leveraging Helmholtz resonance to dissipate energy as heat. With an absorption coefficient (α > 0.9) in the 500–4000 Hz range, it reduces noise by up to 15 dB in applications like EV cabins or noise barriers.

What makes VIBRALON 25 SB effective for soundproofing?
VIBRALON 25 SB’s viscoelastic properties achieve a loss factor (η > 0.2), converting vibrational energy into heat. It reduces structure-borne noise by up to 10 dB, ideal for generator bases, EV battery packs, or barrier foundations, with durability in harsh conditions.

What are the main soundproofing techniques?
Soundproofing techniques include absorption (using materials like Acustimet® to reduce airborne noise), damping (using VIBRALON 25 SB for vibrations), isolation (creating air gaps or decoupling structures), and mass addition (using dense materials to block sound).

Where are Sontech’s soundproofing materials used?
Our materials are used in electric vehicles (motors, batteries), generators, noise barriers (highways, industrial sites), industrial machinery, and buildings, ensuring noise reduction and compliance with regulations like ECE R138 or EN 1793.

How effective is soundproofing?
Soundproofing can reduce noise by 10–30 dB, depending on materials and techniques. For example, Sontech’s Acustimet® lowers airborne noise by up to 15 dB, while VIBRALON 25 SB reduces structure-borne noise by up to 10 dB, significantly improving comfort.

Can soundproofing completely eliminate noise?
No, soundproofing cannot eliminate all noise, as some sound waves, especially low frequencies, are harder to block. However, Sontech’s solutions can reduce noise to barely perceptible levels, meeting regulatory and comfort standards.

How are Sontech’s soundproofing materials installed?
Acustimet® panels are typically mounted on surfaces like walls, enclosures, or barriers, while VIBRALON 25 SB is applied to vibrating structures like bases or casings. Sontech provides installation guides and collaborates with clients for seamless integration.

Sontech 的隔音材料是可持续的吗？
Yes, both Acustimet® and VIBRALON 25 SB are eco-friendly, with recyclable components and compliance with ISO 14001 standards, supporting sustainable noise control solutions.

Can Sontech customize soundproofing materials?
Absolutely. We tailor Acustimet® and VIBRALON 25 SB to specific applications, offering custom thicknesses, sizes, and integration designs for industries like automotive, infrastructure, and manufacturing.

How do I maintain soundproofing materials?
Acustimet® requires minimal maintenance, such as occasional cleaning with a damp cloth to remove dust. VIBRALON 25 SB is durable against environmental factors, needing only periodic inspections for wear in high-vibration settings.

What is the cost of soundproofing?
Costs vary based on project size, materials, and customization. Sontech offers competitive pricing for Acustimet® and VIBRALON 25 SB solutions. Contact us at info@sontech.se 获取量身定制的报价。

Does soundproofing affect aesthetics?
Not with Sontech’s solutions. Acustimet® panels can be customized for color and texture to blend with environments, and VIBRALON 25 SB is applied discreetly to structures, ensuring both functionality and visual appeal.

Is soundproofing only for industrial use?
No, soundproofing benefits residential, commercial, and automotive settings too. Sontech’s materials are used in homes, offices, EVs, and public infrastructure to reduce noise and enhance comfort.
