Insertion loss of an acoustic enclosure

The Journal of the Acoustical Society of America, 2004
Acoustical enclosures are the common arrangements in reducing airborne noise from shipboard machinery such as engines and generators. In this paper the theoretical models, established based on statistical energy analysis, are presented for predicting the insertion loss of acoustical enclosures in different frequency ranges.

On windscreen insertion loss

The Journal of the Acoustical Society of America, 2002
Microphone windscreens are used to attenuate wind noise. They add impedance between the source and microphone, not accounted for when the system is checked by acoustical calibrator or when used in the field. The procedure for the characterization of the attenuation has recently been addressed in ANSI S1.17/2000 part 1.

Insertion loss of mismatched filters

Proceedings of the IEEE, 1975
The design of power line filters is difficult because the actual impedances of the equipment to be suppressed and of the power lines are often unknown. By means of simple geometric considerations it is easy to calculate the maximum and minimum insertion losses which give a more realistic characterization of power line filter performances.

Low-Insertion-Loss and Power-Efficient 32 × 32 Silicon Photonics Switch With Extremely High-Δ Silica PLC Connector

Journal of Lightwave Technology, 2019
We fabricate a 32 × 32 silicon photonics switch on a 300-mm silicon-on-insulator wafer by using our complementary metal-oxide-semiconductor pilot line equipped with an immersion ArF scanner and demonstrate an average fiber-to-fiber insertion loss of 10.8

Insertion Losses of Acoustic Louvers

The Journal of the Acoustical Society of America, 1973
Manufacturers of acoustic louvers usually publish transmission loss data, measured in the laboratory according to ASTM E90-70, for their products. Since field conditions rarely match those specified in ASTM E90-70, insertion loss data would generally be more valuable. Normally, an acoustic louver is used as an alternative to a standard louver. The data

Minimum Insertion Loss Filters

Proceedings of the IRE, 1957
A generalized criterion is given for the design of minimum loss Butterworth and Tchebycheff filters of arbitrary bandwidth and component quality. This criterion is chosen to minimize the insertion loss in the center of the band and is particularly useful for microwave filters, where insertion loss must be minimized.

Measurement of the insertion loss of a single microbend

Optics Letters, 1981
An experiment is reported that demonstrates the ability of the optical-time-domain reflector (OTDR) to locate and characterize small waveguide perturbations. Single microbends, as small as 10 microm in amplitude, were located and characterized. The experiment indicates a potential new application for the OTDR characterization of waveguide perturbations.

Aluminum Nitride Lamb Wave Delay Lines With Sub-6 dB Insertion Loss

Journal of microelectromechanical systems, 2019
We present a group of low-loss Lamb mode acoustic delay lines in an aluminum nitride (AlN) thin film. The low-loss acoustic delay lines are enabled by the thickness-field-excited single-phase unidirectional transducers.
