Sennheiser SpeechLine – True to the word

Sennheiser SpeechLine – T rue to the word

The spoken word remains the most personal and powerful tool in communication. It enables us to convey and exchange messages, thoughts and opinions, as well as emotions. Therefore, when using technical devices like microphones, it is most important that no content is lost or misunderstood.

The best microphone is one you don‘t have to think about while speaking, because it fully captures your voice and picks up your words as precisely as you form them. Easy operation a nd cl ear speech intelligibility are perhaps most popularly embodied in the characteristically shaped Sennheiser ME 36, which can be seen on virtually every TV news program.

The qualities of these iconic microphones can also b e found in all other microphones of the versatile Sennheiser SpeechLine series. These qualities are also built into any microphone of the versatile Sennheiser SpeechLine portfolio.

Wired or wireless, digital or analog , this comprehensive range of easy t o integrate and unobtrusively designed microphones offer a solution for just about any situation, including yours.

In many applications, a speech microphone can help to increase the speech intelligibility or even make it possible in the first place (as in teleconferences). The following chapters describe the most common applications.

Typical applications

A) Conferences (voice lift)

The larger the room, the more helpful is an au the speech intelligibility. Especially in large conference rooms, a speaker seated at one end is difficult to understand at the other end. Table or ceiling microphones can be used to pick up what the speaker says. The audio signal can then be spread evenly around the room using wall or ceiling loudspeakers. This application is also known as “voice lift”, i.e. the speech is amplified in the room.

B) Teleconferences

e participants of a conference are seated in dif

If th to be connected via telephone or remote conference circuit. As a telephone alone can only offer inadequate sp eech tr ansmissi on for all part icipants in the room, table or ceiling microphones should be used in this case too. These are connected to a telephone conference unit such as the Sennheiser TeamConnect system. This processes the signals and establishes the connection to the remote participant.

Presentations

cont room, the more necessary it is to amplify the voice. In this case, gooseneck microphones offer the speaker orientation and enhance his presentation.

Suspending a microphone from the ceiling i

s another alternative. It has the advantage that the microphones can be installed virtually invisibly in the room. Ceiling installation requires precise prior planning, as the microphones are further away from the speaker and the speech intelligibility can be impaired by noise coming from the ventilator of a projector or from an air conditioning unit.

C) Lectern

A lectern is usually used for presentati

ons. Here, too, the microphon es c an be positioned temporarily or installed permanently. A gooseneck microphone positions the microphone capsule close to the speaker, thus ensuring maximum speech intelligibility. Flexi ble gooseneck microphones prevent conflicts with laptops because they can be oriented flexibly.

D) Floor

For spontaneous presentations or panel dis

cussions, floor stands provide a

solid base for a gooseneck microphone.

Pick-up patterns of the microphones

Omni-directional pick-up pattern

An omni-directional pattern picks up the sound uniformly from all directions.

Cardioid pick-up pattern

A cardioid pattern has a wide directional characteristic, i.e. a wide opening angle. Sound hitting the rear of the microphone is attenuated very strongly.

ME 34

MEG 14-40

Super-cardioid pick-up pattern

A super-cardioid pattern has a slightly stronger directional characteristic than the cardioid pattern, so it suppresses noise coming from the side even more strongly but also picks up some of the sound coming from the rear.

Super-cardioid | lobar pick-up pattern

A super-cardioid or lobar pattern has the s tr ongest directional characteristic, i.e. it provides the maximum suppression of sound coming from the side, but it also picks up sound coming from the rear. However, the ratio is lower than it is with the super-cardioid pattern.

Positioning the microphones

A) Distance from the speaker

Basically, the nearer a speaker is to the microphone, the higher the speech

ligibility. For this reason, gooseneck microphones are optimal from an

intel acoustic point of view. They position the microphone capsule close to the speaker while offering excellent orientation.

Boundary layer microphones do not achieve the excellent acoustic characteristics of gooseneck microphones, but they can be positioned especially unobtrusively. These microphones can be integrated into any room due to their small size and the colors they are available in. As a result of the so-called boundary layer effect, the signal picked up by the microphone capsule is amplified on a surface (for example a table or a ceiling panel). In this way, part of the distance to the speaker can be compensated for again.

6 | SpeechLine IS microphone series

B) One microphone for each speaker

In the ideal case, a dedicated microphone is used for each speake

r. This allows the best possible orientation and distance to the speaker to be ensured at all times. It is also possible to choose a narrower directional characteristic. This allows noise coming from the side as well as acoustic reflections to be minimized, resulting in the highest speech intelligibility.

C) “Shared microphones” - several sp

One microphone per speaker is ideal, but

eakers share one microphone

one microphone shared by two speakers is often adequate for many applications. A microphone with a sufficiently wide opening angle should be selected here. Th e microphone can thus pick up both speakers if installed centrally before them.

Sennheiser SpeechLine – True to the word

D) Typical table shapes - U-shaped, round, long, rows

Depending on the configuration of the tables in a room, different

icrophones can be selected. In the case of a small round table, for

m example, a microphone with an omni-directional pick-up pattern (shown as a blue circle) is adequate to pick up all participants uniformly. Directional microphones (shown as a semicircle) are suitable for rows of tables. These microphones minimize the sound coming from the rear and the sides. In oblong conference rooms with long tables, a combination of directional and omni-directional microphones can be a good solution.

E) Speaker is seated

For conferences in which the speakers ar distance between the speaker and the microphone is easy to estimate or measure. Here, the microphone is simply placed on the table and oriented towards the speaker.

e seated, planning is easy as the

F) Speaker is standing

In the case of presentations held at a standing position. Here, the distance between lectern and mouth is virtually as large as it is with a seated speaker. In courtrooms, the speakers frequently stand up although the table in front of them is often of “normal” height. In this case, long gooseneck microphones should be used ideally in order to reduce the distance between the microphone capsule and the speaker.

lectern, the speaker is usually in a

Sennheiser SpeechLine – True to the word

Typical acoustic situations

A) Normally attenuated room

A normally attenuated room provides an average attenuation of reflecti ceilings. In the case of reduced reflections in the room, microphones pick up less noise, which results in the highest speech intelligibility.

B) Room with amplified sound

If the speech in the room is amplified by the microphone again. This can cause echo, but in the worst case acoustic feedback can be the result. The effect can be reduced by using microphones with stronger directional characteristics.

C) Large rooms with echo – acoustically challenging rooms

loudspeakers, this signal can enter

The larger the room, the more probable i reflections or sound coming from loudspeakers. If the room also has many smooth surfaces such as glass fronts or smooth floors, the result is a scenario which is extremely unfavorable acoustically. In this case, only microphones with strong directional characteristics like the ME 36 can ensure speech intelligibility.
