Use this Buyer's Guide for a cost-effective voice amplifier that meets your teachers' expectations in 2024.

In purchasing amplifiers, there are many parameters to consider, here we have listed 12 purchase selections for customer reference.   

Selection 1: The Use of the Amplifier Classroom Area

Before shopping for a voice amplifier, consumers need to know how much area the number of teachers and students is. Because different power amplifiers' amplification effects are not the same, the location of amplification is also different. The classroom area is related to the amplifier output power and sound transmission distance, but also the consumer needs to consider it. These are also the parameters of the amplifier, in different power amplifiers, these parameters are not the same.

First of all, for kindergarten teachers, Our recommended amplifiers are the output power 5-10W amplifiers, the reasons for the recommendation are that the output power 5-10W amplifier is suitable for the applicable site area is within 40 meters, kindergarten classrooms, and the number of people generally in this range, so this type of power amplifier is the most suitable.

Depending on the size of the primary/secondary school classroom and the number of students in the classroom, we recommend 10-15W amplifiers for primary/secondary school teachers, because the applicable site area is within 80 meters, and the classrooms and numbers of primary and secondary schools are generally within this range, so this type of power amplifier is the most suitable.

Depending on the size of the university or outdoor classroom and the number of students in the classroom, we recommend 25W and 30W+ amplifiers for teachers in university or outdoor teaching scenarios because of the long sound transmission distance of these high-powered amplifiers, which can reach 1000 square feet.

Selection 2: The Number of Students

Customers can choose the power of the amplifier on the number of students in their classroom. The power of different amplifiers varies, as well as the effect and quality of amplification. So teachers of different ages can choose the most suitable amplifiers for themselves by their teaching scenarios and the number of students in their classes.

For kindergarten teachers, our recommended amplifier is the output power of the 5-10W amplifier, the reason for the recommendation is that the output power of the 5-10W amplifier is suitable for the number of students 30-80, the number of kindergartens is generally in this range, so this type of amplifier is the most suitable.

According to the size of the primary/secondary school classroom and the number of students in the classroom, we recommend 10-15W amplifiers for primary/secondary school teachers, because the number of students applying to amplifiers with an output power of 10-18W is 80 120, and the classrooms and number of students in primary and secondary schools are generally within this range, so this type of amplifier is the most suitable.

For the number of students at university or outdoor teaching, we recommend 25W and above amplifiers for university or outdoor teaching teachers, as these high-power amplifiers allow 180 people to hear clearly.

Selection 3: How Should Customers Buy Wired or Wireless Amplifiers?

For customers who want to purchase wired or wireless amplifiers, we introduce the advantages of wired and wireless amplifiers or applications that do not easily use wired and wireless amplifiers. For teachers to choose wired or wireless amplifiers for use in the classroom based on the above advantages.

Advantages of wired amplifiers:

1. The wired amplifier is lightweight, compact, and portable.

2. Operation is straightforward, even if you could without needing the manual. Just plug and play.

Selection 9: Voice Amplifier for Online or Offline Teaching

Due to the global pandemic, teachers are one of those who face difficulties and challenges when teaching their students. Today, classes are done either offline or online. If there’s one helpful gadget that assisted teachers during this time, they are the voice amplifier!

Voice amplifiers can assist teachers in the new normal manner of teaching in the following ways:

Speak loud and clear

Voice amplifiers will assist teachers in exerting less effort in their delivery of teachings to be discussed with their students. Voice amplifiers will perform the work for them instead of giving their lectures loudly or manually amplifying their voices.

As a result, teachers will not strain their voices while giving lessons since they can speak quietly, and the voice amplifier will deliver a clear and loud message to the students.

Reduce your mental stress

One of the most formidable obstacles that a teacher must overcome is stress. It’s impossible to avoid, especially when pupils don’t receive or understand what the teacher is saying, resulting in a barrage of questions.

However, it may have an impact on their ability to teach in the future. Voice amplifiers can reduce mental stress since they will present lectures to the students loud and clear, and the teacher will have confidence in all of their efforts in discussing how well the students understood the lessons.

Learning that is more efficient

Teachers can deliver loud and clear lessons to pupils by utilizing the voice amplifier, which provides the highest audio quality for improved learning. Students will be able to hear the information without any sound barriers, typically caused by low-quality audio output from some microphones on teachers’ devices.

Examples include those utilized in online classes, which will be established as the ‘new normal’ mode of schooling in pandemic situations.

The presentation is similar to that of a classroom

Suppose the teacher prefers to use a chalkboard, whiteboard, charts, or any other teaching approach. In that case, the voice amplifier can be worn on the waistband and used to discuss the lesson with the connected microphone if the teacher has a blackboard at home.  

Because the voice amplifier is also equipped with Bluetooth, the teacher can use the wireless microphone. The teacher can pick between the two options based on their preferences.

The best voice amplifier has a variety of features that can be used simultaneously. Let us discuss the different functions you can get from a voice amplifier:

Bluetooth Connectivity

The latest technology for Bluetooth connectivity gives an excellent experience to its users. Voice amplifiers and amplified systems carry a top-notch performance when it comes to Bluetooth connection. Take note that not all Bluetooth voice amplifiers have the same quality when it comes to sound output. When choosing the best voice amplifier, check all the functions that come with it such as the wattage and connectivity coverage.

Battery and Power Life

Chargeable devices are more useful and economical instead of using disposable batteries or rechargeable batteries. If you want a long-lasting voice enhancer device, choose one with a battery life of at least 5-8 hours or more.

Voice amplifiers have enduring and durable batteries so you can use them for a longer time. Since the charging cables are mostly USB-port capable, you can have more options in getting it re-charged.

With rechargeable batteries, there are no more messy wires when you use them. Wireless gadgets are very convenient and even the charging cables are just long enough to be kept in a small case. They are very portable you don’t need other adapters or cables to make it work.

Noise Cancellation

A wireless voice amplifier’s circuit design should minimize white noise and undesired ambient sounds, allowing you to have a wonderful and fulfilling listening experience! It should filter out and cancel out background disturbances so that you don’t have to crank up the volume to hear the sound.

For wireless headsets or microphones, the active noise-canceling function may reduce excessive or unwanted noise because its structure provides a barrier that filters high-frequency sound waves. This way, the noise is reduced by actively eliminating or filtering lower-frequency sound waves.

Added Features and Functions

Aside from amplifying your voice, there are basic and enhanced features that you can get from a voice amplifier. It comes with a built-in recorder, FM radio, TF/micro SD card port, Aux and USB ports, etc. There are specific functions that you can get from different models, so you can only buy the unit that will fit your needs.
