Omnidirektionale Mikrofone

An omnidirectional microphone is designed to capture sound equally from all directions (360 degrees). This makes it ideal for recording ambient sound, group discussions, or any situation where sound comes from multiple sources around the microphone.

Omnidirectional microphones are widely used in applications such as conference rooms, environmental recording, voice recognition devices, and surveillance systems.

Unterschied zwischen omnidirektionalen und unidirektionalen Mikrofonen

The main difference lies in their pickup patterns:

• Omnidirectional microphones pick up sound evenly from all around the microphone capsule.
• Unidirectional microphones (such as cardioid or supercardioid) focus on capturing sound primarily from one direction, minimizing noise from other directions.

Choosing between them depends on your application needs. If you want to capture sound from multiple sources or directions, omnidirectional is preferred. For isolating sound from a specific source, unidirectional microphones are better.

An omnidirectional electret microphone capsule is designed to pick up sound equally from all directions, making it ideal for capturing ambient sound or voice from multiple angles. These capsules are commonly used in applications like voice recorders, wearable devices, and surveillance systems.

When equipped with an IP67 waterproof rating, the microphone is sealed to resist both dust and water—fully protected against dust ingress and capable of withstanding immersion in up to 1 meter of water for 30 minutes. This combination is ideal for demanding environments such as:

• Outdoor surveillance
• Smart doorbells
• Wildlife recording systems
• Wearable and lavalier microphones

Here are some of our recommended IP67-rated omnidirectional models:

• ECM-B9745AL30RC-IP67 – 9.7mm capsule for outdoor security cameras
• ECM-B4015AP40-IP67 – 4mm capsule for compact outdoor microphone modules
• ECM-F9745AL36-IP67 – 9.7mm capsule for lavalier or wearable use

High sensitivity capsules (e.g., -25dB to -26dB) are designed for long-range sound capture or picking up low-volume signals. These omnidirectional types are commonly used in conferencing systems, remote monitoring, and parabolic microphone setups.

• ECM-B6027AP25-382 – 6mm capsule for conference microphones
• ECM-B9750AL26-062-L15 – 9.7mm capsule for remote pickup or high gain applications
• ECM-B6027AL26-941 – 6mm back electret capsule with strong output
• ECM-B9750AL26-062 – Suited for parabolic microphone dishes

A microphone with a flat frequency response is designed to pick up all frequencies within its range evenly, without boosting or cutting specific bands. This ensures a natural, accurate reproduction of sound—ideal for capturing the true tonal character of the source.

Flat response microphones are especially preferred for:

• Acoustic instrument recording
• Live performance capture
• High-fidelity ambient recordings
• Sound measurement and analysis

For example, our ECM-B5820AML40-522 Und ECM-B5820AL36-522 are both optimized for smooth frequency response across the audible spectrum.
