When building an anechoic chamber, choosing between a fully anechoic chamber or a semi-anechoic chamber is an important decision that requires consideration of multiple factors, including budget, needs, usage scenarios, etc. The following will analyze the advantages and disadvantages of choosing a fully anechoic chamber or a semi-anechoic chamber from different angles to help you make a more informed decision.

Budget: Fully anechoic rooms usually require the use of high-performance sound-absorbing materials for comprehensive sound-absorbing treatment, so the construction cost is relatively high. In contrast, a semi-anechoic chamber only requires sound-absorbing treatment in key areas. Generally, the floor is not sound-absorbing, so the construction cost will be more economical. If your budget is limited, consider choosing a semi-anechoic chamber.

Requirements: If you need an acoustic environment with absolutely no reflection echoes, such as for high-fidelity audio recording or precision acoustic experiments, then a fully anechoic chamber may be a better choice. Fully anechoic chambers provide the highest level of acoustic control, ensuring there are no echoes or reflections of sound. If it is just to reduce noise or echo in the general environment, a semi-anechoic chamber may be enough. A fully anechoic room has 6 surfaces that are sound-absorbed, that is, the top surface, four walls, and ceiling are all equipped with sound-absorbing spikes. In this way, the 6 surfaces will absorb the sound emitted by the sound source without reflection. A semi-anechoic room has only five sides with sound-absorbing treatment, and the floor is not equipped with sound-absorbing spikes. It is usually the original cement floor of the room, with sound-insulating carpets or tiles laid on it. Therefore, the floor of the semi-anechoic chamber forms a reflective surface, which is also the substantial difference between full anechoic chamber and semi-anechoic chamber.

Usage scenarios: Depending on the specific usage scenarios of the anechoic chamber, the choice of a full anechoic chamber or a semi-anechoic chamber will also differ. For example, for places with extremely high acoustic environment requirements, such as high-precision acoustic laboratories, a fully anechoic chamber may be a more suitable choice. For general acoustic experiments, recording studios, home audio-visual rooms, etc., semi-anechoic rooms may be enough to meet daily needs.

Choosing a fully anechoic chamber or a semi-anechoic chamber depends on your budget, needs and usage scenarios. If you are looking for the highest level of acoustic control and have the budget, a fully anechoic chamber may be a better choice; if the budget is limited or the acoustic environment is not very demanding, a semi-anechoic chamber may be more cost-effective. Before making a decision, it is recommended that you carefully evaluate your needs and seek the advice of a professional acoustic engineer to ensure you select the most appropriate type of anechoic chamber to meet your needs.
